To a solution of N-methyl-3-(2-methyl-1H-indol-5-yl)-3-phenyl-acrylamide LXVIII (990 mg, 3.41 mmol) in EtOH/EtOAc/MeOH (5/2/1, 40 ml) was added Pd/C (5%, 90 mg). The mixture was hydrogenated in a Parr apparatus at 60 psi of H2 for 48 hours. Degoussa-type catalyst (10% Pd/C, catalytic amount) was added to the mixture. The mixture was hydrogenated in a Parr apparatus at 60 psi of H2 for additional 6 hours. The reaction mixture was filtered through celite, and the filter cake was washed with MeOH, hot EtOH and DCM. The filtrate was concentrated affording N-methyl-3-(2-methyl-1H-indol-5-yl)-3-phenyl-propionamide LXIX as a light orange foamy solid in quantitative yield (1.05 g).
