21.9 parts of 2-benzyloxy-1,3-dichloro-propane, 45.1 parts of monoethylamine and 45.1 parts of water were added to an autoclave and the mixture was heated at 90° C. for 48 hours with agitation. The reaction mixture was cooled and treated in the same manner as in Example 29, followed by distillation under reduced pressure. As a result, 11.6 parts of 3-benzyloxy-1-ethylazetidine boiling at 73°-74° C. under 2 mm Hg were obtained. The yield was 61%. The results of infra-red spectrum analysis and nuclear magnetic resonance analysis of the product are as follows:
