反应详情

The mixture of [4-(tert-butyl-dimethyl-silanyloxy)-2-methyl-phenyl]-methyl-carbamic acid benzyl ester (14.0 g, 36.0 mmol) and palladium on carbon (10 wt %, 0.5 g) in methanol (100.0 mL) is stirred under an atmosphere of hydrogen at room temperature overnight. The reaction mixture is filtered and the filtrate is concentrated under reduced pressure to a residue. The residue is purified by flash chromatography to afford the title compound as oil (7.4 g, 81%). LC-ES/MS m/e 252.3 (M+1).
