Procedure

Compound 312 (200 mg, 0.701 mmol) was dissolved in DMF (3.5 mL), and isonicotinic acid (259 mg, 2.10 mmol), EDC hydrochloride (403 mg, 2.10 mmol) and 1-hydroxybenzotriazole monohydrate (322 mg, 2.10 mmol) were added thereto, followed by stirring at 60° C. for 3 hours. The reaction mixture was poured into water, followed by extraction with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was recrystallized from 2-propanol to afford the entitled Compound 313 (170 mg, 62%).
