Reaction Steps

[4-Amino-5-(2-benzyl-2H-indazol-6-yl)-pyrrolo[2,1-f][1,2,4]triazin-7-yl]-(1,2,3,4-tetrahydro-isoquinolin-7-yl)-methanone (0.050 g, 0.01 mmol) was dissolved in dichloromethane (1 mL) and methanesulfonic acid (0.104 mL, 1.61 mmol) was added followed by Et3SIH (0.128 mL, 0.80 mmol). The resulting mixture was stirred at rt overnight. The mixture was diluted with dichloromethane and washed with saturated aqueous NaHCO3, water and brine. The organic layer was concentrated, suspended in MeOH and filtered to give a desired product as white solid (30 mg, 62%). 1H-NMR (CD3OD-d4) 8.28-8.24 (m, 1 H), 7.78 (s, 1 H), 7.70 (dd, 1H), 7.59-7.56 (m, 1 H), 7.33-7.23 (m, 5 H), 7.11 (dd, 1 H), 7.07-6.89 (m, 3 H), 6.39 (s, 1 H), 5.57 (s, 2 H), 4.16 (s, 2 H), 3.82 (s, 2 H), 2.96 (t, 2 H), 2.71 (t, 2 H); LC-MS [M+H]+=486.3, RT=2.30 min.
