Reaction Steps

To a solution of crude tert-butyl {3-[({6-[2-(benzylamino)-2-oxoethyl]-1-benzothien-2-yl}carbonyl)amino]-1-phenyl-1H-pyrazol-4-yl}carbamate (from step A) in ethyl aceate (10 mL) and methanol (10 mL) was added 4M HCl in dioxane (10 mL) and the resulting solution was stirred for 16 hours at ambient temperature. The reaction was evaporated to dryness and purified by reverse phase LC to give 148 mg (40%, 2 steps) of N-(4-amino-1-phenyl-1H-pyrazol-3-yl)-6-[2-(benzylamino)-2-oxoethyl]-1-benzothiophene-2-carboxamide as a white solid. 1H NMR (DMSO-d6) δ 11.01 (s, 1H), 8.59 (t, J=5.87 Hz, 1H), 8.35 (s, 1H), 7.89 (t, J=3.82 Hz, 2H), 7.80 (s, 1H), 7.67 (d, J=7.92 Hz, 2H), 7.42 (t, J=7.33 Hz, 2H), 7.36 (d, J=9.1 Hz, 1H), 7.28 (t, J=7.92 Hz, 2H), 7.19 (m, 4H), 4.25 (d, J=5.87 Hz, 2H), 3.61 (s, 2H). ESIMS calcd 482.2 (M++H), found 482.1 (M++H).
