実験手順: According to the method disclosed in EP-982300, Example 78, sodium 3-piperidinopropanolate (2.127 kg; 12.88 mol), 3-(4-chlorophenyl)propyl mesylate (1.121 kg; 4.51 mol) and 0.322 mol of 15-crown-5 in 4.5 kg of dry toluene were refluxed for 4 hours. The solvent was evaporated and the residue purified by column chromatography on silica gel (eluent: methylene chloride/methanol (90/10)). The obtained oil was distilled in a fractionating equipment at reduced pressure (0.3-0.7 mmHg) and with a heating jacket at 207-210° C. The head fractions and the distilled fraction at 0.001-0.010 mmHg with a jacket temperature of 180-200° C. were collected. The obtained oil (1.0 kg; 3.38 mol) corresponds to 1-[3-[3-(4-chlorophenyl)propoxy]propyl]-piperidine. Yield 75%. were refluxed for 4 hours The solvent was evaporated the residue purified by column chromatography on silica gel (eluent: methylene chloride/methanol (90/10)) The obtained oil was distilled in a fractionating equipment at reduced pressure (0.3-0.7 mmHg) and with a heating jacket at 207-210° C The head fractions and the distilled fraction at 0.001-0.010 mmHg with a jacket temperature of 180-200° C. were collected

実験手順: A solution of 49.5 g. of ethyl 4-aminobenzoate, 34.9 g. of 3-(p-chlorophenyl)propanol O-mesylate in 100 ml. of hexamethylphosphoramide is heated at 125°-130° C. for 16 hours. The solution is diluted with 50 ml. of tetrahydrofuran and with 150 ml. of water. Chilling and filtering gives crystals which are washed with water and recrystallized from ethanol to give 28.3 g. of light yellow crystals. Recrystallizations give the product as crystals, m.p. 122°-124° C. The solution is diluted with 50 ml Chilling filtering gives crystals which are washed with water recrystallized from ethanol to give 28.3 g Recrystallizations
