실험 절차

Triethylamine 0.12 ml was added in a methylene chloride 10 ml solution of (1S)-1,8,8-trimethyl-3-azabicyclo[3.2.1]octane hydrochloride 100 mg and stirred at 0° C. for 30 min. 9-bicyclo[3.3.1]nonylacetic acid 97.0 mg and WSC 0.15 g were added therein, then temperature of the reaction mixture was gradually changed to room temperature and stirred for 19 hours. The reaction mixture was washed with saturated aqueous sodium chloride solution and dried by anhydrous sodium sulfate. After filtering the drying agent, the filtrate was concentrated in vacuo to obtain crude (1S)-3-(bicyclo[3.3.1]nonan-9-yl)acetyl-1,8,8-trimethyl-3-azabicyclo[3.2.1]octane. The concentrate was added to THF 10 ml solution of lithium aluminum hydride 41 mg and refluxed under heating for 1 hour. The reaction mixture was cooled, then water was added thereto and the insoluble material was removed by filtration. The filtrate was concentrated in vacuo. The thus obtained residue was purified by means of silica gel column chromatography (Wako gel, C200, chloroform:acetone=10:1-5:1) to obtain the product.
