Reaction Steps
To a stirring solution of 2-(6-methoxy-[1,5]naphthyridin-4-yl)-4,5,6,7-tetrahydro-2H-indazol-5-ylamine (50 mg, 0.17 mmol) and 3-phenylpropionaldehyde (20 mg, 0.2 mmol) in dichloroethane (2 mL) was added NaB(OAc)3H (37 mg, 0.17 mmol) and acetic acid (2 drops). The reaction mixture was stirred overnight at RT. Water (5 mL) was added, and the aqueous layer was extracted with CH2Cl2 (3×15 mL). The combined organic layers were washed with brine (10 mL), dried (MgSO4), filtered, and concentrated. The crude material was purified on SiO2 (0-5% CH3OH/CH2Cl2) to give 24 mg (36%) of the title compound as a clear oil. MS (ESI): exact mass calculated for C25H27N5O, 413.22; m/z found, 414.5 [M+H]+. 1H NMR (400 MHz, CDCl3): 9.07 (s, 1H), 8.72-8.70 (m, 1H), 8.25-8.23 (m, 1H), 8.08-8.07 (m, 1H), 7.30-7.21 (m, 5H), 7.18-7.16 (m, 1H), 4.09 (s, 3H), 3.06-2.90 (m, 3H), 2.80-2.68 (m, 5H), 2.46-2.40 (m, 1H), 2.19-2.16 (m, 1H), 1.93-1.86 (m, 2H), 1.77-1.67 (m, 1H).
