Reaction Steps

Imidazole-2-carboxaldehyde (0.011 g, 0.112 mmol) and [7-(2-methoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl]-(2-methoxy-4-piperidin-4-yl-phenyl)-amine (53 mg, 0.12 mmol) were treated with sodium triacetoxyborohydride (0.033 g, 0.157 mmol) and acetic acid (0.064 mL, 0.112 mmol) in tetrahydrofuran (0.900 mL) at room temperature overnight. The reaction mixture was then concentrated and partitioned between dichloromethane and a saturated aqueous sodium bicarbonate solution. It was dried on NaSO4, filtered and concentrated. The product was isolated by reverse phase hplc (Gilson) to afford {4-[1-(1H-imidazol-2-ylmethyl)-piperidin-4-yl]-2-methoxy-phenyl}-[7-(2-methoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl]-amine as a yellow foam (5 mg, 9%). 1H-NMR (CDCl3) δ 9.63 (s, 1H), 8.69 (s, 1H), 8.29 (d, J=8.7 Hz, 1H), 8.00 (d, J=6.2 Hz, 1H), 7.44 (m, 2H), 7.13 (m, 1H), 7.07 (d, J=8.3 Hz, 1H), 7.02 (s, 2H), 6.83 (d, J=4.7 Hz, 1H), 6.73 (m, 2H), 3.89 (s, 3H), 3.84 (s, 3H), 3.71 (s, 2H), 2.97 (d, J=11.4 Hz, 2H), 2.49 (m, 1H), 2.25 (m, 2H), 1.85 (m, 5H); LC/MS (ESI+): 510.2 (M+H).
