A round bottom flask was charged with (R)-2-(5-nitro-1-oxoisoquinolin-2(1H)-yl)propyl acetate (24 g, 0.074 mol), ethanol (500 mL, 8 mol), and was heated at 85° C. Ammonium chloride (50 g, 0.9 mol) in water (150 mL, 8.3 mol) was added followed by iron (20 g, 0.3 mol) in two portions. The reaction was stirred for 1 hour and poured onto dichloromethane (200 mL) and extracted. the solvent was removed under reduced pressureunder reduced pressure to afford the desired product as red oil (19 g, 100%).
