실험 절차

To a solution of 4-[3-phenyl-5-(1H-pyrazol-4-yl)-1,6-naphthyridin-2-yl]benzaldehyde (1-3) (0.11 g, 0.29 mmol) in NMP (10 mL) was added 3-amino-2,2-dimethylpropan-1-ol (0.030 g, 0.29 mmol) and acetic acid (0.026 g, 0.43 mmol). After stirring at room temperature for 2 hours, sodium triacetoxyborohydride (0.092 g, 0.43 mmol) was added and the reaction was stirred at room temperature for 15 hours. The reaction was poured into saturated sodium bicarbonate and extracted with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered and concentrated under vacuum. Purification by reverse phase chromatography (5-95% acetonitrile/water/0.1% TFA; Water Sunfire C18) gave 2,2-dimethyl-3-({4-[3-phenyl-5-(1H-pyrazol-4-yl)-1,6-naphthyridin-2-yl]benzyl}amino)propan-1-ol (1-4) as a off white solid. HRMS (M+H)+: calculated 464.2207; found 464.2194
