A stirred solution of 3.9 g (0.015 mole) of 3-(2-chloro-6-methylphenoxy)-1-azetidinecarbonyl chloride in 20 mL of tetrahydrofuran was treated all at once with 2.8 mL (0.045 mole) of 57% ammonium hydroxide. After stirring for 72 h the reaction mixture was diluted with 200 mL of water and the precipitated product collected by filtration (3.6 g of pale yellow product). Recrystallization from benzene yielded 2.8 g (69.2%) of fine white crystals, mp 256°-157° C.
