実験手順

To a mixture of enantiomer 2 of 4-{1-ethyl-1-[4-(2-hydroxy-3,3-dimethyl-butoxy)-3-methyl-phenyl]-propyl}-N-methoxy-2,N-dimethyl-benzamide (0.76 g, 1.75 mmol) and THF (20 mL) is added 1M LAH in THF (1.75 mL, 1.75 mmol) with cooling, and the solution stirred for 1 hour. The solution is diluted with Et2O (100 mL) and washed with 1M HCl (50 mL). The aqueous phase is extracted with Et2O (50 mL). The combined organic layers are washed with 1M HCl (50 mL), brine (50 mL), dried over MgSO4, filtered and concentrated to furnish the title compound (0.48 g, 1.21 mmol, 73%).
