Reaktionsschritte
90 g (2.37 mole) of lithium aluminum hydride in 200 ml of diethyl ether were slowly added with stirring to a solution of 231 g (1.37 mole) of methyl quinuclidine-3-carboxylate of Example 4 in 1,000 ml of diethyl ether. Reflux was continued for 3 hours and the excess lithium alanate was carefully decomposed with 500 ml of water with proper cooling. The reaction mixture was filtered and after separation of the phases, the ether phase was dried over magnesium sulfate. Thereafter, the ether was distilled off to obtain 116 g (0.82 mole) of quinuclidine-3-methanol (60% yield) as a colorless oil.
