Procedure

A solution of 9.6 g (0.025 mole) of 3-(4-trifluoromethylphenoxy)azetidine 56.66% (contains diphenylmethane) in 50 ml of acetone was treated with 4.22 g (0.045 mole) of nitro urea and 5 ml of water. The mixture washeated on a hot plate until a clear solution was obtained then allowed to cool to ambient temperature during the next 4 hr. The reaction was diluted with 200 ml of ice water and an oil separated (diphenylmethane) which was dissolved in 30/60 petroleum ether and separated. Upon standing, a fine white precipitate formed in the aqueous solution. Filtration yielded 3.6 g of fine white crystals, m.p. 176°-178° C. After drying under 0.5 mmHg vacuum at 80° C., the product weight was reduced to 3.1 g, m.p. 178°-179° C.; yield was 47.7%
