Reaction Steps

A round bottom flask was charged with methyl 2-(4-chlorophenyl)-2-(5-nitro-1-oxoisoquinolin-2(1H)-yl)acetate (4.2 g, 0.011 mol) ethanol (60 mL, 1 mol) and ammonium chloride (6 g, 0.1 mol) in water (60 mL, 3 mol) was added and the reaction heated at 80° C. and iron (2 g, 0.04 mol) was added in four portions 5 minutes apart. The reaction was heated for another 1 h at that temperature and cooled to room temperature and poured into 200 ml dichloromethane and extracted. The solvent was removed to obtain the product as a light brown solid. MS m/z=343.0 (M+H).
