Reaction Steps

By procedures described in Example 1 (Method A), β-methyl-phenethylamine and benzoyl chloride were converted to 4-methyl-1,2,3,4-tetrahydroisoquinoline. A reaction vessel was charged 4-methyl-1-phenyl-1,2,3,4-tetrahydroisoquinoline. A reaction vessel was charged with 3.0 g of this isoquinoline compound, 5 ml 10% sodium hydroxide and 50 ml methylene chloride. With this mixture stirred, 2 ml dichloroacetyl chloride was added dropwise to the mixture. The mixture was stirred for 5 minutes, then water was added. The organic extract was dried with magnesium sulfate, stripped of solvent and subjected to Kugelrohr distillation (160° C. @ 0.1 mm Hg) to provide 4 g of a yellow oil product having the elemental analysis reported in Table I.
