Participants

Reaction Steps

Acetaldehyde (6.76 mg, 0.15 mmol) in dichloroethane (5 mL, 2 equiv) was added to 1-(2-Phenyl-quinolin-7-yl)-3-piperidin-4-ylmethyl-imidazo[1,5-a]pyrazin-8-ylamine (100.00 mg, 0.23 mmol) and sodium triacetoxyborohydride (65.0 mg, 306.8 mmol). The reaction mixture was stirred at rt overnight. The crude product was purified by a 5 g Jones silica gel (dry loaded with silica, wetted with 100% CH2Cl2, eluted with 100% CH2Cl2→3% (7N NH3) in MeOH/CH2Cl2→6% (7N NH3) in MeOH/CH2Cl2) and afforded the desired product. 1H NMR (400 MHz, METHANOL-d) δ 8.38 (1 H, d, J=8.66), 8.25 (1 H, s), 8.08 (2 H, dd, J=1.64 Hz, J=1.08), 8.00 (2 H, m), 7.79 (1 H, dd, J=2.06, J=1.70), 7.51 (1 H, d, J=5.15), 7.44 (3 H, m), 7.00 (1 H, d, J=5.12), 3.06 (2 H, d, J=10.88), 2.97 (2 H, d, J=7.08), 2.54 (2 H, d, J=5.80), 2.18 (2 H, m), 1.98 (1H, m), 1.75 (2 H, d, J=13.12), 1.43 (2 H, m), 1.07 (3 H, t); MS (ES+): m/z 435.12/436.10 (15/5) [MH+]; HPLC: tR=1.71 min (OpenLynx, polar—5 min).
