A process for preparing 3-phenoxyazetidines uses a phase transfer catalyst to add the phenoxy group to azetidine blocked in the 1-position by a diphenylmethane group and uses a stabilizing tertiary amine base to prevent dimerization during hydrogenolysis to remove the blocking group. The crude product containing diphenylmethane may be used without purification to prepare 3-phenoxy-1-azetidine carboxamides. |
