Abstract
The application discloses a novel improved process for the production of .alpha.-[2-(p-chlorophenoxy)-isobutyl]-.beta.-nicotinoyl glycol ester, a known compound having a lipid-lowering effect, by the reaction of .alpha.-[2-chlorophenoxy)-isobutyryl]-.beta.-ethyl chloride ester with an alkali salt of nicotinic acid, preferably sodium nicotinate, preferably in a high-boiling polar or dipolar aprotic solvent, especially dimethylformamide, most preferably at a temperature of about 120.degree. - 180.degree. C., and most advantageously in refluxing dimethylformamide. An unpredictable increase in yields of the desired product over yields attainable by previously-available processes is thereby obtained.
