To prepare N- (3-cyano-5,6,7,8-tetrahydro-4H-cycloheptano [b] thiophene-2-yl) pyridine-3-formamide, there are three methods.
First, pyridine-3-carboxylic acid is used as the starting point. Pyridine-3-carboxylic acid is first co-heated with sulfinyl chloride to obtain pyridine-3-formyl chloride. After that, pyridine-3-carboxylic chloride is reacted with 3-amino-5,6,7,8-tetrahydro-4H-cycloheptano [b] thiophene-2-formonitrile in the presence of a base (such as triethylamine) in a suitable solvent (such as dichloromethane), and the temperature is controlled to obtain the product. The raw materials are easy to obtain in this way, but the activity of pyridine-3-formyl chloride is high, and the operation needs to be cautious to prevent side reactions.
Second, 3-bromopyridine is used as a base. First, 3-bromopyridine and magnesium chips are prepared in anhydrous ethyl ether to obtain Grignard's reagent, and then reacted with 3-cyano-5,6,7,8-tetrahydro-4H-cycloheptano [b] thiophene-2-formaldehyde to obtain an alcohol intermediate. Then oxidize to aldehyde with a suitable oxidant (such as Dyce-Martin oxidant), and then react with ammonia or ammonium salt to obtain the target by amidation. This step is slightly more complicated, but the conditions are mild and the selectivity is good.
Third, start with 5,6,7,8-tetrahydro-4H-cycloheptano [b] thiophene-2-amine. First, 5,6,7,8-tetrahydro-4H-cycloheptano [b] thiophene-2-amine and 3-cyanopyridine-2-carboxylic acid are reacted in a suitable solvent (such as N, N-dimethylaminopyridine) under the action of a condensation agent (such as carbodiimide) and a catalyst (such as 4-dimethylaminopyridine), and the condensation product is obtained. This way the reaction is direct, the yield may be high, but the cost of some condensation agents is higher.
