methyl 13-cyclohexyl-6-(benzyloxycarbonyl)-5H-indolo[2,1-a][2]benzazepine-10-carboxylate → 13-cyclohexyl-10-methoxycarbonyl-6,7-dihydro-5H-indolo[2,1-a][2]benzazepine-6-carboxylic acid

Reaction Steps

Method A: The intermediate ester (14, R=H, 53 mg, 0.13 mmol) in a 1:1 mixture of THF/MeOH (2 mL) was treated with a catalytic amount of Pd (10% on C) under hydrogen (balloon pressure). The mixture was stirred at 22° C. for 18 hr. The catalyst was removed by filtration through a fine pad of celite and the solution was concentrated in vacuo to afford the title compound as a pale tan solid (50 mg, 92%). ESI-MS m/z 418 (MH+).
