Abstract

1295539 Preparation of viquidil salts SOC GENERALE DE RECHERCHES ET D'APPLICATIONS SCIENTIFIQUES SOGERAS 19 April 1971 [6 May 1970] 21830/70 Heading C2C The neutral di-(p-toluyl)-d-tartrate salt of viquidil may be obtained by reacting viquidil or a salt thereof, respectively, with di-(ptoluyl)-d-tartaric acid or a salt thereof, in solution in a solvent in which both reactants are soluble, and separating the salt formed from the reaction mixture. The preferred solvent is methanol and the viquidil starting material may be obtained by the ring opening and isomerization of quinine or quinidine. The viquidil free base may be liberated from the di-(ptoluyl)-d-tartrate salt, e.g. in acidic or alkaline medium, and treated with acids to form other viquidil salts.
