Reaction Steps

To a solution of (3-benzyloxy-2-ethoxy-phenyl)-(1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-methanol (664, 195 mg, 0.37 mmol) in a mixture of methanol (20 mL) and tetrahydrofuran (50 mL) was added palladium on carbon (50 mg, 10% wt., 0.2 mmol). The mixture was stirred under hydrogenation for seventeen hours. After removal of solvent, the residue was washed with a mixture of ethyl ether and hexanes to provide the compound as a white solid (665, 63 mg, 95%). MS(ESI) [M+H+]+=439.37.
