Triethylamine → N-(2-methylcyclopentyl)-3,5-difluoro-4-(2-propynyloxy)benzamide

Participants

Reaction Steps

A mixture of 0.12 g of 2-methylcyclopentylamine, 0.2 ml of triethylamine and 1 ml of ethyl acetate was added dropwise under ice cooling to a mixture of 1 ml of ethyl acetate and 0.23 g of 3,5-difluoro-4-(2-propynyloxy)benzoyl chloride. The mixture obtained was stirred at room temperature for 12 hours. Then, the reaction mixture was subjected to silica gel column chromatography to obtain 0.07 g of N-(2-methylcyclopentyl)-3,5-difluoro-4-(2-propynyloxy)benzamide (hereinafter, described as the compound 54 of the present invention) represented by the formula:
