A reaction vessel was charged with 4 g of this isoquinoline compound, 10 ml 10% sodium hydroxide and 50 ml methylene chloride. With this mixture stirred, 1.1 equivalents dichloro-acetyl chloride was added dropwise to the mixture. The mixture was stirred for 15 minutes, then water was added. The organic extract was dried with magnesium aulfate, and stripped of solvent, and subjected to Kugelrohr distillation (150° C. @0.25 mm Hg) to provide 4.5 g of a yellow oil product having the following elemental analysis:
