The synthesis method of Ethyl 4- (trifluoromethyl) pyridine - 3 - carboxylate (4- (trifluoromethyl) pyridine - 3 - carboxylate ethyl ester) covers a variety of paths.
One of them can be started by a compound containing a pyridine ring. First, take an appropriate pyridine derivative and introduce trifluoromethyl at a specific position in the pyridine ring. The nucleophilic substitution reaction can be used to select a suitable trifluoromethylation reagent, such as trifluoromethyl halide or an active reagent with trifluoromethyl, and under appropriate base and reaction conditions, the introduction of trifluoromethyl can be achieved. Subsequently, another position on the pyridine ring is modified by carboxyl ethylation. The target product 4- (trifluoromethyl) pyridine-3-carboxylic acid ethyl ester can be obtained by esterification reaction with ethanol and suitable esterification reagents, such as acyl chloride or acid anhydride, in the presence of a catalyst.
Second, it can also be synthesized by the strategy of constructing a pyridine ring. Small molecules containing suitable substituents are selected to construct a pyridine ring through a multi-step reaction. For example, under suitable reaction conditions, a pyridine ring is formed by condensation, cyclization, etc. Then, the carboxyl group on the pyridine ring is ethylated, which can be achieved by reaction with ethanol and corresponding esterification reagents.
Third, the reaction catalyzed by transition metals can also be considered. For example, using halogenated pyridine derivatives as raw materials, under the catalysis of transition metal catalysts such as palladium and copper, the coupling reaction occurs with trifluoromethylation reagents and reagents containing ethoxy carbonyl groups. The transition metal catalyst can activate the reaction substrate and promote the reaction to proceed efficiently, so that Ethyl 4- (trifluoromethyl) pyridine-3-carboxylate can be prepared directly or through several steps. Each synthesis method has its own advantages and disadvantages, and the appropriate synthesis path needs to be weighed according to the actual situation, such as the availability of raw materials, the difficulty of reaction conditions, cost and yield.

In terms of chemical properties, it contains an ester group and has ester properties. When it encounters a strong acid or a strong base, a hydrolysis reaction can occur. Hydrolysis under acidic conditions will produce 4- (trifluoromethyl) pyridine-3-carboxylic acid and ethanol; hydrolysis under alkaline conditions will produce corresponding carboxylate and ethanol. < Br >
Because of the trifluoromethyl group attached to the pyridine ring, the trifluoromethyl group has strong electron-absorbing properties, resulting in a decrease in the electron cloud density of the pyridine ring. This property changes the electrophilic substitution reactivity of the pyridine ring, and it is more likely to react at a relatively high electron cloud density position than the general pyridine. At the same time, the electron-withdrawing group also affects the ester group, which enhances the positive electricity of the carbonyl carbon in the ester group, or changes the hydrolysis reactivity.
In addition, the bonding mode between the atoms and the distribution of the electron cloud in this compound determine its chemical stability and the balance of reactivity. Although trifluoromethyl enhances partial stability, ester groups are relatively active and can still participate in various organic reactions under suitable conditions, which is a key property that can be used in organic synthesis.

I don't know the exact price of ethyl 4- (trifluoromethyl) pyridine - 3 - carboxylate on the market. The price of this compound often varies due to a variety of reasons.
