Reaction Steps

[4-Amino-5-(2-benzyl-2H-indazol-6-yl)-pyrrolo[2,1-f][1,2,4]triazin-7-yl]-pyrrolidin-3-yl-methanone hydrochloride salt (89 mg, 0.19 mmol) was dissolved in dichloromethane (1 mL) and triethylamine (0.079 mL, 0.56 mmol) was added, followed by methanesulfonyl chloride (0.022 mL, 0.28 mmol). The mixture was stirred at it for 18 h and then at 50° C. overnight. The mixture was concentrated, diluted with MeOH, filtered and the filtrate purified by HPLC eluting with 20-95% gradient acetonitrile/water to afford 24 mg (25%) of the title compound. 1H-NMR (CD2Cl2-d2) 8.13-8.06 (m, 2 H), 7.81 (dt, 1H), 7.77-7.76 (m, 1 H), 7.43 (s, 1H), 7.42-7.33, (m, 5 H), 7.19 (dd, 1 H), 5.64 (s, 1 H), 4.61-4.53 (m, 1 H), 3.74-3.65 (m, 2 H), 3.54-3.44 (m, 1 H), 3.39-3.31 (m, 1 H), 2.89 (s, 1 H), 2.46-2.28 (m, 2 H); LC-MS [M+H]+=516.2, RT=2.88 min.
