실험 절차
A 1.6 N solution of BuLi in hexane (1.12 ml, 1.79 mmol) was added dropwise to a solution of 3-ethynyl-1-azabicyclo[2.2.2]octan-3-ol 47 (123 mg, 0.81 mmol) in THF (5 ml) at room temperature. After stirring for 30 minutes, (4-methoxyphenyl)(2-thienyl)methanone (231 mg, 1.06 mmol, commercial) in THF (1 ml) was added slowly. After 2 hours, the reaction was quenched by addition of saturated aqueous NH4Cl solution and diluted with AcOEt. The organic phase was washed with brine, dried over Na2SO4 and evaporated. The yellowish oil was purified by chromatography on silica gel (CH2Cl2/MeOH 85/15) and 3-[3-hydroxy-3-(4-methoxyphenyl)-3-(2-thienyl)-1-propynyl]quinuclidin-3-ol 152 was obtained as a white solid (41 mg, 14%, mixture of diastereomers).
