Procedure
To a stirred and chilled (15°-20° C.) solution of 0.024 mole of 3-[3-(trifluoromethyl)phenoxy]azetidine in 50 ml of dry benzene was added dropwise 1.99 g (0.028 mole) of ethyl isocyanate. The reaction mixture was stirred at room temperature overnight and was diluted with 50 ml of methylene chloride. The solution was washed with 5% sodium hydroxide (2×50 ml), water (50 ml), saturated sodium chloride (25 ml), dried over sodium hydroxide, and concentrated in vacuo. The residue (9.6 g) was twice recrystallized from ethyl acetate-isopropyl ether to give 5.4 g of a white solid, m.p. 125°-126° C.
