Procedure

DIPEA (601 μl) was added to a solution of 1-ethyl-4-oxo-5-phenyl-1,4-dihydropyridine-3-carboxylic acid (420 mg) and COMU (961 mg) in DMF (5.0 ml) at room temperature, and the mixture was stirred for 20 minutes. The compound obtained in Step 2 of Example 1 (610 mg) was added at room temperature. The mixture was stirred for 15 hours, followed by the addition of water. The organic layer was extracted with ethyl acetate, and then washed with water and brine and dried over sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography [chloroform:methanol=300:1->60:1 (v/v)] to give 700 mg of the title compound as a solid.
