Phenethylamine → 2-(Dichloroacetyl)-1-phenyl-1,2,3,4-tetrahydroisoquinoline

참여 물질

반응 단계

By procedures described in Example 1 (Method A), phenethylamine and benzoyl chloride were converted to 1-phenyl-1,2,3,4-tetrahydroisoquinoline. A reaction vessel was charged with 3.5 g of this isoquinoline compound, 10 ml 10% sodium hydroxide and 50 ml methylene chloride. With this mixture stirred, 1.2 ml dichloroacetyl chloride was added dropwise to the mixture. The mixture was stirred for 10 minutes, then water was added. The organic extract was dried with magnesium sulfate and stripped of solvent. The residue was recrystallized from ethanol to provide 4 g of a white cubic-crystal product having the elemental analysis reported in Table I.
