반응 단계

A mixture of 1.45 g of 7-azabicyclo[4.1.0]heptane, 2 ml of triethylamine and 3 ml of ethyl acetate was added dropwise to a mixture of 10 ml of ethyl acetate and 2.3 g of 3,5-difluoro-4-(2-propynyloxy)benzoic acid chloride under ice-cooling. The resulting mixture was stirred at room temperature for 4 hours. The reaction mixture was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 1.8 g of 7-[3,5-difluoro-4-(2-propynyloxy)benzoyl]-7-azabicyclo[4.1.0]heptane represented by the formula:
