Versuchsvorschrift

To a solution of 7.5 g (28 mmole) of 1-(diphenylmethyl)azetidine-3-carboxylic acid in 75 ml of acetonitrile was added 6.0 g (37 mmole) of 1,1'-carbonyldiimidazole. The reaction was heated at 60° C. for two hours and successively treated with 3.1 g (30.8 mmole) of triethylamine and 2.52 g (30.8 mmole) of ethylamine hydrochloride. The reaction was stirred at 60° C. for an additional hour, the solvent evaporated in vacuo and the residue dissolved in chloroform. After washing with water and drying over magnesium sulfate, the chloroform layer was evaporated in vacuo to give 9.4 g of 1-(diphenylmethyl)-N-ethyl-3-azetidinecarboxamide, mp 91°-93° C.
