Procedure

A mixture of 20 g of 2-phenoxyethyl bromide thus obtained, 7.92 g of piperidine and 12.86 g of potassium carbonate was added into 100 ml of ethyl alcohol and stirred for 6 hours at 100° C. The mixture obtained was filtered and condensed under reduced pressure to give 18.4 g of 1-(2-phenoxyethyl)piperidine having a boiling point of 111° C. to 112° C. at 7 mmHg in a yield of 90%.
