Reaction Steps
A solution of 4-iodo-2-methoxynicotinic acid (1.95 g) obtained in Step C of Example 6, cyclopentylhydrazine hydrochloride (1.05 g), EDCI hydrochloride (0.58 g), HOBt (2.01 g) and triethylamine (1.06 g) in DMF (30 mL) was stirred at room temperature for 3 days. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (697 mg).
