Reaction Steps

1-{[5-(1-Hydroxyethyl)-2-methoxy-6-methylpyridin-3-yl]aminocarbonyl}-4-(3,5-dimethoxyphenyl)piperazine(107 mg, 0.25 mmol) and dimethylaminopyridine(3 mg, 0.025 mmol) were dissolved in pyridine and anhydrous succinic acid(50 mg, 0.5 mmol) was added. The mixture was stirred at room temperature for 5 hrs. Distilled water was added into the above mixture. The above solution was extracted with CH2Cl2 and the organic phase washed with 1N-HCl and then concentrated under the reduced pressure to remove the solvent. The concentrate was purified by column chromatography(dichloromethane:methanol=20:1) to obtain the titled compound.
