A mixture of 1-fluoro-4-methoxycarbazole (438 mg, 2.04 mmol) and pyridine hydrochloride (3 g) was placed into an oil bath that was preheated to 220° C. After 20 minutes, the reaction was poured onto a mixture of ice and concentrated ammonium hydroxide. The product was extracted into ethyl acetate and the extract was dried over magnesium sulfate, filtered, and concentrated in vacuo.
