실험 절차
4-Chlorobutyryl chloride in dichlormethane was added to an ice cooled solution of piperidine (1.8 ml; 17.6 mmol) and triethylamine (2.5 ml) in dichloromethane (40 ml) under an atmosphere of nitrogen. The mixture was stirred for 5 min whilst being cooled, then stirred at ambient temperature for 3 h. The solution was washed with water, dried over sodium sulfate and evaporated to give 1-(4-chloro-1-oxobutyl)piperidine as a pale yellow oil (2.1 g).
