实验步骤: A solution of [2-(t-butyldiphenylsilyloxy)ethyl]carbamic acid benzyl ester (3.01 g, 6.9 mmol) (obtained as described in Reference Example 33(1)) in methanol (150 ml) was subjected to catalytic hydrogenation in the presence of 20% palladium hydroxide on charcoal (3.0 g) at room temperature. After checking the completion of the reaction, the reaction mixture was filtered in order to remove the catalyst and the filtrate concentrated under reduced pressure. The residue was purified by chromatography on a silica gel column using methylene chloride:methanol (10:1) as the eluant to afford 2-(t-butyldiphenylsilyloxy)ethylamine (1.49 g, yield 72%) as a pale brown syrup. the completion of the reaction the reaction mixture was filtered in order to remove the catalyst the filtrate concentrated under reduced pressure The residue was purified by chromatography on a silica gel column
