Procedure
To a solution of 5-acetyl-6-methyl-4-(3-nitrophenyl)-2-pyridinecarboxylic acid (0.95 g) in tetrahydrofuran (10 ml) was added N-hydroxybenzotriazole (0.43 g) and N-ethyl-N'-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.61 g) at 5° C. After the mixture was stirred at the same temperature for 1 hour, 2-morpholinoethylamine (0.41 g) and triethylamine (0.32 g) was added thereto. The mixture was stirred at ambient temperature for 2 hours and diluted with ice-cold water (20 ml) and ethyl acetate (20 ml). The separated organic layer was washed with brine, dried and concentrated in vacuo. The residue was triturated with diethyl ether to give 3-acetyl-2-methyl-6-(2-morpholinoethylcarbamoyl)-4-(3-nitrophenyl)pyridine (0.45 g).
