The method of preparing [5- (cetylacyloxy) -6-methylpyridine-3,4-diyl] dimethylglycol dihexanoate is quite ingenious.
First take the appropriate pyridine derivative as the initial material. This pyridine derivative needs to have a modifiable group at a specific position to lay the foundation for the subsequent reaction.
Then, the pyridine derivative reacts with hexadecyl chloride under suitable reaction conditions. This process requires careful temperature control, usually in the mild temperature range, and is preferably assisted by suitable catalysts, such as some organic base catalysts, to promote the acylation of hydroxyl groups at specific positions on the pyridine ring with hexadecyl chloride to generate 5- (hexadecyl acyloxy) -6 -methyl pyridine derivatives. This step aims to precisely introduce the hexadecyl acyloxy group.
Furthermore, the resulting product is further reacted with formaldehyde or equivalent methylating reagents under specific conditions to achieve dimethylglycol on the pyridine ring. This reaction has strict requirements on the polarity, pH and reaction time of the reaction solvent, so that the reaction can proceed according to the expected path and accurately generate intermediates containing dimethylglycol structures.
Finally, the intermediate is esterified with hexanoic acid or active derivatives of hexanoic acid, such as hexanoyl chloride, in the presence of a catalyst. This step also requires precise regulation of the reaction parameters to ensure that both hydroxyl groups of dimethyl glycol can be esterified with hexanoic acid or its derivatives, so as to successfully prepare [5- (cetylacyloxy) -6-methylpyridine-3,4-diyl] dimethyl glycol dihexanoate. After each step of the reaction, suitable separation and purification methods, such as column chromatography, recrystallization, etc., are required to obtain a pure product to ensure the high efficiency of the reaction and the purity of the product.
