Procedure

Compound 399 (102 mg, 0.408 mmol) was dissolved in DMF (5 mL), and isonicotinic acid (199 mg, 1.63 mmol), EDC hydrochloride (309 mg, 1.61 mmol) and 1-hydroxybenzotriazole monohydrate (245 mg, 1.60 mmol) were added thereto, followed by stirring at 60° C. for 1.5 hours. The reaction mixture was concentrated under reduced pressure, and a saturated aqueous solution of sodium hydrogencarbonate was added to the resulting residue, 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 ethanol to afford the entitled Compound 400 (115 mg, 79%) as a pale yellowish green solid.
