Reaction Steps

A mixture of 2-formyl-3-carboxy-1,2,3,4-tetrahydroisoquinoline (20 g) and 1,4-naphthoquinone (30.8 g) in acetic anhydride (500 ml) was heated at 100° C. with stirring for 30 minutes. The reaction mixture was cooled, the solid collected by filtration, washed with acetic anhydride (50 g) with ether (2×100ml) and dried to give the title compound in Form B (26 g).
