実験手順

A solution of 4-(5-methoxy-3-phenyl-1,6-naphthyridin-2-yl)benzaldehyde (80 mg, 0.235 mmol) and 1-piperidin-4-yl-1H-pyrazolo[3,4-d]pyrimidine-4-amine (58 mg, 0.26 mmol) in dry DMF (1 mL) containing acetic acid (70 μL, 1.25 mmol) was stirred at room temperature 16 hours. Sodium triacetoxyborohydride (91 mg, 0.43 mmol) was then added to the semi-solid mixture and stirred for three hours. The mixture was diluted with methanol and the solvent evaporated. The residue was purified by column chromatography on silica gel eluting with a 0.5 to 5% methanol/ethyl acetate (sat'd NH3) gradient. The combined fractions were concentrated and the residue was digested with acetonitrile to afford upon cooling the pure title compound. 1H-NMR (500 MHz, CDCl3): δ 8.55 (1H, s), 8.39 (1H, s), 8.23 (1H, d, J=6 Hz), 7.92 (1H, s), 7.56 (1H, d, J=6 Hz), 7.41 (2H, d, J=7.8 Hz), 7.24-7.33 (5H, m), 5.40 (2H, br s), 4.75 (1H, m), 4.17 (3H, s), 3.57 (2H, br s), 2.31-2.41 (2H, m), 2.18-2.28 (2H, m), 1.96 (2H, br d, J=10.7 Hz). m/e (m+1): 543.3.
