反応手順

0.36 g of 2-[3-(3-thienyl)phenoxy]ethoxyacetic acid was dissolved in 7 ml of tetrahydrofuran, and under ice cooling, 110 μl of methyl chloroformate and 200 μl of triethylamine were added. After the mixture was stirred with cooling for 30 minutes, 178 μl of cyclopropylamine was added. The mixture was stirred at room temperature for 1 hour, and then ethyl ether and water were added. The organic layer separated was worked up in a customary manner to give 0.31 g of N-cyclopropyl-2-[3(3-thienyl)phenoxy]ethoxyacetamide as a pale yellow oil.
