Reaction Steps

A mixture of 4-amino-3-(3-methoxy-4-{[(1-methyl-1H-indol-2-yl)carbonyl]amino}phenyl)-N-(pyrrolidin-2-ylmethyl)thieno[3,2-c]pyridine-7-carboxamide (0.100 g, 0.18 mmol), 2-bromoacetamide (0.03 g, 0.217 mmol) and potassium carbonate (0.05 g, 0.36 mmol) in N,N-dimethylformamide (2 mL) was stirred at ambient temperature for 18 hours. The solvent was removed in vacuo and the residue was purified by preparative RP-HPLC (Hypersil-HS C18, 8 μm, 100 Å, 25 cm; 5-100% acetonitrile-0.1M ammonium acetate over 25 min, 21 ml/min). The acetonitrile was removed in vacuo and the aqueous mixture was lyophilized to give the title compound as a white solid.: 1H NMR (DMSO-d6, 400 MHz) δ 9.50 (s, 1H), 8.56 (s, 1H), 8.44 (t, 1H), 7.98 (d, 1H), 7.69 (d, 1H), 7.58 (d, 1H), 7.58 (s, 1H), 7.35 (m, 3H), 7.15 (m, 3H), 7.06 (d, 1H), 6.0 (bs, 2H), 4.04 (s, 3H), 3.91 (s, 3H), 3.42 (m, 1H), 3.38 (d, 1H), 3.24 (m, 1H), 3.04 (m, 1H), 2.86 (d, 1H), 2.79 (m, 1H), 2.27 (m, 1H), 1.86 (s, 9H), 1.85 (m, 1H), 1.68 (m, 3H); LCMS (Conditions a), Rt 2.88 min.; MS: MH+612.
