Reaction Steps

Compound 447 (150 mg, 0.517 mmol) was dissolved in DMF (2.5 mL), and isonicotinic acid (191 mg, 1.55 mmol), EDC hydrochloride (298 mg, 1.55 mmol) and 1-hydroxybenzotriazole monohydrate (237 mg, 1.55 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 448 (115 mg, 66%).
