Versuchsvorschrift

A solution of 14 g (0.144 mole) of phosgene in 200 ml of methylene chloride was treated with 19.9 g (0.144 mole) of anhydrous potassium carbonate and stirred for 1 hr, then 45.9 g (0.12 mole) of 1-diphenylmethyl-3-(3,4-dichlorophenoxy)azetidine in 100 ml of methylene chloride was added dropwise and stirring was continued for 72 hr. The reaction mixture was filtered to remove the inorganic salts and then concentrated in vacuo to a pale yellow oil (67 g). Trituration of the residue with cyclohexane yielded a crude pale yellow solid (23.6 g). The filtrate was treated with ligroin and upon standing, an additional 13.3 g of tacky material was obtained. After several recrystallizations from cyclohexane to remove traces of diphenylmethyl chloride a portion was obtained as fine white crystals, in 70.1% yield, m.p. 96°-99° C.
