Reaction Steps

A mixture of ethyl 1-(o-tolyl)-1H-indole-3-carboxylate (0.789 g, 2.82 mmol), 4N sodium hydroxide aqueous (20 mL) and tetrahydrofuran (20 mL) was stirred at 60° C. for 18 hours. Most solvent was removed and the rest was acidified with 10% hydrochloric acid aqueous to adjust to pH=5. Pale yellow precipitate formed and was collected by filtration. The solid was washed with petroleum ether, dried in vacuo to give 1-(o-tolyl)-1H-indole-3-carboxylic acid as a pale yellow solid (0.675 g, 95%). LRMS (M+H) m/z: calcd 251.09. found 251.
