Procedure

Trifluoro-methanesulfonic acid 7-(6-methoxy-pyridin-3-yl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl ester (95.0 mg, 0.254 mmol) was dissolved in N,N-dimethylformamide (3.00 mL). N,N-diisopropylethylamine (133 uL, 0.761 mmol) was added followed by 1-methanesulfonyl-1,2,3,4-tetrahydro-quinolin-7-ylamine (80.4 mg, 0.355 mmol) and the reaction was stirred overnight. The reaction was taken up in EtOAc (25 mL) and washed three times with water (25 mL). The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure. Purification by silica gel chromatography using a gradient of 0-70% EtOAc/hex as the eluting solvent to obtain the title compound as a yellow solid (54 mg, 47%). m.p.=202-203° C.; LCMS (m/e) 451 (M+H); 1H-NMR (d6-DMSO, 400 MHz) δ 9.46 (s, 1H), 8.98 (s, 1H), 8.89 (s, 1H), 8.53 (dd, 1H, J=2.2 and 8.7 Hz), 7.81 (s, 1H), 7.53 (d, 1H, J=8.4 Hz), 7.19 (d, 1H, J=4.7 Hz), 7.10 (d, 1H, J=8.4 Hz), 7.02-6.93 (m, 2H), 3.93 (s, 3H), 3.74-3.68 (m, 2H), 2.99 (s, 3H), 2.79-2.72 (m, 2H), 1.97-1.88 (m, 2H).
