A stirred slurry of 6.2 g (0.02 mole of 3-[4-(trifluoromethyl)phenoxy]azetidine oxalate in 60 ml of tetrahydrofuran was treated with 1.8 g (0.022 mole) of 1-methylethyl isocyanate and after 0.5 hr, 5 ml of triethylamine was added. A clear yellow solution was obtained and was stirred for 18 hr, then treated with 10 ml of water, yielding 5.3 g (87.7%) of pale yellow crystals, m.p. 151°-152° C.
