Reaction Steps

A solution of (E)-3-(6-amino-pyridin-3-yl)-N-(3-chloro-4-fluoro-benzo[b]thiophen-2-ylmethyl)-N-methylacrylamide (257 mg, 0.68 mmol) in CH2Cl2 (10 mL) was treated with anhydrous HCl (0.68 mL of a 1.0 M solution in Et2O, 0.68 mmol). The mixture was stirred overnight at room temperature and then diluted with Et2O. The resulting solid was collected by filtration and then dried under vacuum at 50° C. for 2 d to give the title compound (282 mg, 98%) 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), 7.87-7.82 (m, 1H), 7.55-7.20 (m, 4H), 7.04-7.00 (m, 1H), 5.15-4.88 (m, 2H), 3.54 (br s, 1H), 3.22-2.97 (m, 3H); MS (ESI) m/e 376 (M+H)+.
