Participants

Reaction Steps

To a solution of 5-(2-benzyl-2H-indazol-6-yl)-7-(2-piperidin-4-yl-1,3-thiazol-4-yl)pyrrolo[2,1-f][1,2,4]triazin-4-amine hydrochloride (100 mg, 0.17 mmol) in DMF (1.5 mL) was added methanesulfonyl chloride (15 μL, 0.19 mmol) and N,N-diisopropylethylamine (120 μL, 0.69 mmol). The reaction was stirred at rt for 17 h. The crude mixture was purified by preparative HPLC using a gradient elution from 15% to 45% acetonitrile to provide 28 mg (28%) of the desired product. 1H NMR (400 MHz, DMSO-d6) δ 8.56 (s, 1 H), 8.38 (s, 1 H), 8.10 (s, 1 H), 7.83 (d, 1 H), 7.67 (s, 1 H), 7.27-7.40 (m, 5H), 7.17-7.24 (m, 2 H), 5.66 (s, 2 H), 3.59-3.69 (m, 2 H), 3.16-3.28 (m, 1 H), 2.85-2.95 (m, 5H), 2.20 (d, 2 H), 1.78 (q, 2 H); ES-MS m/z 585.21 [M+H]+, HPLC RT (min) 2.97.
