Reaction Conditions

Reaction Steps

A mixture of compound 77 (158 mg, 0.83 mmol), NH4Cl (666 mg, 12 mmol) and Iron Powder (463 mg, 8.3 mmol) in water (5 mL) and CH3OH (5 mL) was stirred at 90° C. for 1 h. After cooling, the reaction mixture was filtered and the solid was washed by DCM. The filtrates were separated, the organic layer was washed with brine, dried over Na2SO4 and concentrated to dryness to give compound 78 (100 mg, 75%) as a light yellow oil. 1H NMR (400 MHz, CDCl3) δ8.04 (s, 1H), 6.90-7.00 (m, 2H), 3.53 (br s, 2H), 2.83 (t, 2H, J=7.1 Hz), 2.36 (t, 2H, J=7.1 Hz), 2.02-2.12 (m, 2H).
