実験手順
To a solution of 6-aminonicotinic acid methyl ester (4 g) in pyridine (40 ml) is added with stirring 2-methylbenzoyl chloride (6.73 g) under ice-cooling, and the mixture is stirred at room temperature overnight. To the reaction solution is added water, and the precipitated crystals are collected by filtration, and dried to give 6-(2-methylbenzoylamino)nicotinic acid methyl ester (5.7 g) as white powder.
