Reaction Steps
A solution of 4-iodo-2-methoxynicotinic acid (558 mg), cyclohexyl hydrazine hydrochloride (362 mg), EDCI hydrochloride (575 mg), HOBt (405 mg) and triethylamine (304 mg) in DMF (10 mL) was stirred overnight at room temperature. 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 (515 mg).
