Procedure

To a solution of {2-[7-(2-methanesulfonyl-vinyl)-1H-indol-3-yl]-1,1-dimethyl-ethyl}-carbamic acid tert-butyl ester (0.40 g, 1.02 mmol) in methanol (20.0 mL) is added 10% Pd/C (0.10 g) in methanol (2.0 mL). The reaction mixture is purged with hydrogen and hydrogenation is carried out with a hydrogen balloon overnight. The reaction mixture is filtered and the filtrate is evaporated to dryness to give 320 mg of {2-[7-(2-methanesulfonyl-ethyl)-1H-indol-3-yl]-1,1-dimethyl-ethyl}-carbamic acid tert-butyl ester (80%). FDMS m/e=395.2 (M++1).
