Procedure

To a solution of 1-chloro-6-methoxy-3-methyl-4-phenylisoquinoline (0.24 g) in 20 mL DMF was added benzenesulfinic acid, sodium salt dihydrate (0.60 g). The reaction was heated at 120 C overnight, then poured into water and extracted with EtOAc (3×). The combined organic solutions were washed with water (1×) and brine (1×), dried (Na2SO4) and concentrated. To a solution of the residue in 20 mL DMF was added benzenesulfinic acid, sodium salt dihydrate (0.74 g). The reaction was heated at 160 C overnight, then poured into water and extracted with EtOAc (3×). The combined organic solutions were washed with water (1×) and brine (1×), dried (Na2SO4) and concentrated. The residue was recrystallized from ethyl ether/hexanes, then further purified by flash chromatography (5% to 30% EtOAc/hexanes). A second recrystallization from ethyl ether/hexanes gave the titled compound.
