Reaction Steps

A mixture of 50 g (0.157 mol) of 1-benzhydryl-3-mesyloxyazetidine (J. Org. Chem. 1972, 37, 3953-3955) and 23.5 g (0.479 mol) of sodium cyanide in 340 ml of dimethylformamide and 43 ml of water is heated to 60° C. for 5 hours. The reaction mixture is left at ambient temperature overnight and is then poured into 2000 ml of water/ice. The solid product is recovered by filtration and is purified by being suspended in 800 ml of water and being filtered. The product thus obtained is dried and crystallized from isopropyl ether to obtain 20 g of 1-benzhydryl-3-azetidinecarbonitrile. M.p. 142°-146° C.
