Reaction Steps

A round bottom flask was charged with (R)-2-(6-chloro-5-nitro-1-oxoisoquinolin-2(1H)-yl)propyl acetate (160.0 mg, 0.0004927 mol) and ethanol (7 mL, 0.1 mol) and the reaction heated at 85° C. Ammonium chloride (264 mg, 0.00493 mol) in water (7 mL, 0.4 mol) was then added followed by the addition of iron (110 mg, 0.0020 mol) in two portions. The reaction was heated at that temperature for another hour. The reaction mixture was poured into dichloromethane (60 mL) and extracted. The extracts were washed with brine, dried over sodium sulfate and the solvent removed under reduced pressure to obtain the product as a colorless solid. MS m/z=295.5 (M+H).
