反応手順

A stirred solution of 2.9 g (0.011 mole) of 3-(2-chloro-4-fluorophenoxy)-1-azetidinecarbonyl chloride in 20 mL of tetrahydrofuran was treated with 4 mL (0.05 mole) of 40% aqueous monomethylamine and stirred for 16 hr. The reaction mixture was diluted with 200 mL of water. The solid which precipitated was collected by filtration (2.7 g). The crude product was recrystallized from benzene/ligroin yielding 2.4 g (84.3%) of fine white crystals, mp 139°-141° C.
