Procedure

A solution of compound 15 (1.5 g, 3.79 mmol) in methanol (50 mL) was purged with argon for 20 minutes. Ammonium formate (2.33 g, 37.87 mmol) was then added and the solution was purged for another 10 minutes. Pd—C (10%; 216 mg) was added and the reaction mixture was heated at reflux for 3 hours. The reaction mixture was filtered through the Celite® reagent and washed with methanol. The filtrate was concentrated and the crude material was purified by chromatography on 230-400 mesh silica gel eluting with 2% methanol-DCM to provide compound 16.
