実験手順

A solution of 35.6 g (0.36 mole) of phosgene in 200 ml of methylene chloride at 5° C. was stirred with 50 g (0.36 mole) of potassium carbonate for 1 hr. To the mixture was added dropwise 115 g (0.3 mole) of 1-diphenylmethyl-3-[-3-(trifluoromethyl)phenoxy]azetidine in 400 ml of methylene chloride. After stirring for 18 hr, the reaction mixture was filtered and the filtrate was washed with water, dried over magnesium sulfate and concentrated on a rotary evaporator to a viscous oil residue, 133.2 g. Trituration of the residue with hexane gave a solid which was recrystallized from cold hexane to yield 52 g (62%) of white crystals, m.p. 72.5°-74° C.
