Reaction Steps

A suspension of (E)-3-(6-amino-pyridin-3-yl)-N-(3-chloro-7-fluoro-benzo[b]thiophen-2-ylmethyl)-N-methylacrylamide (105 mg, 0.28 mmol) in CH2Cl2 (10 mL) was treated with anhydrous HCl (0.28 mL of a 1.0 M solution in Et2O, 0.28 mmol) and then the mixture was stirred at room temperature overnight. The mixture was diluted with Et2O. The resulting solid was collected by filtration and dried under vacuum at 50° C. overnight to give the title compound (111 mg, 96%) as an off-white solid and as a mixture of amide rotamers: 1H NMR (300 MHz, DMSO-d6) δ 8.43-8.33 (m, 4H), 7.67-7.52 (m, 3H), 7.41-7.35 (m, 1H), 7.25-7.19 (m, 1H), 7.04-7.01 (m, 1H), 5.21-4.92 (m, 2H), 3.63 (br s, 1H), 3.23-2.98 (m, 3H); MS (ESI) m/e 376 (M+H)+.
