Reaction Steps

A rbf charged with dimethyl 1-(4-fluorobenzyl)-1H-indole-2,3-dicarboxylate (3.79 g, 11.10 mmol) was treated with a solution of KOH (7.48 g, 133 mmol) in Ethanol (13.88 ml) (0.5 M solution) and heated to reflux (95° C. bath temp). After 18 h, the reaction mixture was cooled to ambient temperature, and acidified to pH 1 with 4M HCl and extracted with EtOAc. The organic layer was washed with brine, dried (MgSO4), filtered and concentrated to afford 1-(4-fluorobenzyl)-1H-indole-2,3-dicarboxylic acid (3.0 g, 9.58 mmol, 86% yield) as a yellowish solid. LCMS (m/z) ES+=314 (M+1).
