Process for the preparation of certain alkaloid alcohol esters of tropic acid |
| abstract |
AN IMPROVED PROCESS FOR THE PREPARATION OF A PURE ALKALOID ALCOHOL ESTER OF TROPIC ACID COMPRISING THE FORMATION OF AN ALKALOID ALCOHOL ESTER OF A-FORMYL-PHENYLACETIC ACID BY ESTER INTERCHANGE FOLLOWED BY REDUCTION OF THE ESTER INTERCHANGE PRODUCT, WHICH CONSISTS OF HEATING AN INERT ORGNAIC SOLVENT TO ITS BOILING POINT, SIMULTANEOUSLY ADDING TO THE BOILING SOLVENT A SOLUTION OF AN A-FORMYLPHENYL-ACETIC ACID LOWER ALKYL ESTER IN THE SOLVENT AND A SOLUTION OF AN ALKALOID ALCOHOL IN THE SOLVENT, WHILE CONTINUOUSLY DISTILLING OFF A VAPOR MIXTURE CONISTING OF THE SOLVENT AND A LOWER ALKANOL AT SUBSTANTIALLY THE SAME VOLUMETRIC RATE AS THE SAID SOLUTIONS ARE BEING ADDED, AND REDUCING THE ALKALOID ALCOHOL ESTER OF A-FORMYL-PHENYLACETIC ACID FORMED THEREBY WITH AN ALKALI METAL BOROHYDRIDE. |
