실험 절차

A solution of 4-chlorobutyryl chloride (5.3 mL, 47.4 mmol) in dichloromethane (400 mL) was added dropwise to a mixture of 1-benzyl-4-(isopropylamino)piperidine (10 g, 43.07 mmol) and DIPEA (9.0 mL, 51.7 mmol) in dichloromethane (200 mL) at 0° C. The reaction mixture was stirred at 0° C. for 15 min and then at room temperature for 2 h. The solution was then washed with saturated sodium bicarbonate, brine, dried over magnesium sulfate and concentrated in vacuo. The residue was purified by flash column chromatography (ethyl acetate/hexane/triethylamine: 42.5/56.5/1) to give 5.0 g of the title intermediate as viscous oil (35% yield).
