Participants

Reaction Steps

To a solution of (3-acetyl-5-benzyloxy-indol-1-yl)-acetic acid tert-butyl ester (MS: 380.0 [M+H]+; tR (HPLC conditions c): 5.72 min; prepared from 5-benzyloxy-1H-indole [1215-59-4] in a similar manner as described in Scheme A13 (step A and B)) (3.3 g, 8.70 mmol) in CH2Cl2/MeOH (80 mL) was added Pd/C (0.093 g, 0.870 mmol). The reaction mixture was stirred at RT for 5 h under H2 atmosphere. The reaction mixture was filtered over a pad of Celite and washed with CH2Cl2 and MeOH. Volatiles were evaporated, and the crude mixture was purified by flash chromatography on silica gel (gradient c-hexane/EtOAc 2:1 to 100% EtOAc). TLC, Rf (c-hexane/EtOAc 1:1)=0.35; MS: 312.0 [M+Na]+; tR (HPLC conditions c): 4.27 min.
