Reaction Steps

2-Methyl-5-nitro-2H-isoquinolin-1-one (0.69 g, 0.0032 mol) and tin dichloride dihydrate (2 g, 0.01 mol) were stirred in tetrahydrofuran (10 mL, 0.1 mol) at room temperature overnight. The mixture was purified via flash chromatography (40 g of silica gel, 50% EtOAc/Hexanes) to give a brown solid. MS m/z (M+H) 174.9.
