methyl 3-acetyl-6-chloro-1H-indole-5-carboxylate → 3-acetyl-6-chloro-1H-indole-5-carboxylic acid

Participants

Reaction Steps

A solution of methyl 3-acetyl-6-chloro-1H-indole-5-carboxylate (0.21 g, 0.84 mmol) in 1.5 N sodium hydroxide (0.7 mL) and dioxane (0.5 mL) was heated at 60 C for 6 h and stirred overnight at room temperature. The reaction was quenched by the addition of acetic acid and diluted with water. The resulting solid was filtered, washed with water and dried in vacuo to give the title compound (0.17 g, 96%) as pale yellow powder, m/z=238 (M+H).
