Procedure

To a suspension of 99 (30 mg, 0.058 mmol) in EtOH (1.6 ml) and water (0.6 ml) was added ammonium chloride (3 mg, 0.9 eq, 0.053 mmol) and Fe (28 mg, 8.5 eq, 0.49 mmol) and the reaction mixture was heated to reflux for 45 min. The reaction mixture was cooled to RT, filtered through celite then concentrated to afford title compound 100 (30 mg, 100% yield). MS (m/z): 484.1 (M+H).
