Subsequently, 3.13 g of the 1-benzyl-3-methyl-4-piperidone obtained above was dissolved in 6 ml of ether. The solution was added dropwise to a suspension of 0.44 g of lithium aluminum hydride in 25 ml of ether over 5 minutes while maintaining the temperature at 24°-27° C. Then, the mixture was stirred at 25° C. for 10 minutes, and, 5 ml of water was added thereto under ice-cooling. The mixture was extracted with 30 ml of ether four times.
