A solution of 18.9 g (0.05 mole) of crude 3-[3-(trifluoromethyl)phenoxy]azetidine (contains an equal molar amount of diphenylmethane) in 100 ml of isopropyl ether was stirred under nitrogen while 4.16 g (0.05 mole) of 2-propenyl isocyanate was slowly added. The reaction mixture which was somewhat turbid, cleared and after 1 hr a fine crystalline precipitate began to form. After stirring for 18 hrs, the product was removed by filtration, washed with fresh isopropyl ether and air dried to yield 9.5 g of white crystals, m.p. 75°-76° C.
