Procedure

A mixture of 1.44 g of 2-amino-5-tert-butylphenol, 1.07 g of isonicotinic acid, 2.17 g of WSC and 15 ml of pyridine was stirred while heating at 80° C. for five hours. The reaction mixture was cooled to room temperature, and then water was poured. Precipitated solid was filtered and washed with water and diethyl ether to give 1.22 g of N-(4-tert-butyl-2-hydroxyphenyl)isonicotinamide.
