  • Process for the manufacture of pure isoquinoline derivatives
    Patent number: 4126615
    Abstract: In the production of perparine or papaverine and their hydrochlorides, the formation of impurities in the reaction mixture is suppressed by fractionating a 3,4-di-R-benzyl-cyanide in the presence of an organic base (e.g. pyridine, dimethylformamide, ethylenediamine or triethylamine) followed by hydrogenation with a Raney-nickel catalyst treated with aqueous ammonium carbonate solution. R is methoxy or ethoxy.
