A mixture of 9H-carbazole-3-carboxylic acid (300 mg, 1.42 mmol), K2CO3 (800 mg) and methyl iodide (1 mL) in 25 mL of acetone was heated under reflux overnight, then cooled and evaporated in vacuo. A mixture of the resultant residue and NaOH (170 mg) in aqueous MeOH (90%, 25 mL) was stirred at 50° C. for 30 minutes. The reaction mixture was concentrated and acidified with diluted HCl. The solids were collected by filtration and dried to give the title compound (280 mg, 87%).
