Reaction Steps

A mixture of 6-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-nicotinic acid hydrazide (300 mg, 0.6 mmol) and acetamidine hydrochloride (87 mg, 0.9 mmol) in DMF (6 mL) was heated at 120° C. for 2 h. A second portion of acetamidine hydrochloride (174 mg, 1.8 mmol) was added. After 8 h the mixture was cooled to room temperature and diluted with ethylacetate (40 mL). The mixture was filtered and the filtrates collected and washed with water (3×10 mL) and brine (10 mL) then dried over sodium sulfate, filtered and concentrated. Purification by chromatography (SiO2, 0-5% dichloromethane:methanol=100:0 to 95:5) followed by purification by HPLC (acetonitrile:water=2:8) gave the title compound (42 mg, 20%) as a white solid. MS: m/e=348.2 [M+H]+.
