실험 절차

To a suspension of methyl (2E)-3-{5-[(3R)-3-pyrrolidinylamino]-2-pyrazinyl}acrylate dihydrochloride (240 mg) in CH2Cl2 (2.4 mL) was added DIEA (260 uL), 2-(dimethylamino) benzaldehyde (122.6 mg), and sodium triacetoxyborohydride (317 mg), which was stirred at room temperature for 15 hours. To the resultant was added saturated NaHCO3 aq., which was stirred for 20 min. The mixture was extracted with CH2Cl2. The organic phase was washed with brine and dried over Na2SO4, filtered, and evaporated in vacuo. The residue was washed with hexane to give methyl (2E)-3-[5-({(3R)-1-[2-(dimethylamino)benzyl]-3-pyrrolidinyl}amino)-2-pyrazinyl]acrylate as a beige powder.
