Procedure
Hydroxylamine hydrochloride (0.5 g, 7.2 mmol) in methanol (2 mL) was mixed with KOH (0.4 g, 7.2 mmol) in methanol (2 mL) at 0° C., and sonicated for 2 minutes and the white precipitate formed was filtered. The filtrate was added to methyl 3(4-((4-(1E)-(3-(cyclopropylamino)-2-(4-fluorophenyl)-3-oxoprop-1-enyl)benzamido)methyl)phenyl)acrylate (0.20 g, 0.4 mmol) in DCM (1.5 mL) and the mixture stirred at room temperature for 30 minutes. The reaction mixture was diluted with water (200 mL) and extracted with ethyl acetate (3×100 mL). The ethyl acetate layers were washed with water (100 mL), dried over anhydrous Na2SO4 and concentrated to obtain a crude compound, which was triturated with DCM (15 mL) to obtain a solid which was filtered and washed with DCM (5 mL) to afford the title compound (0.050 g, 25% yield). 1H NMR (DMSO-d6) δ (ppm): 0.51-052 (2H, m, —CH2), 0.63-0.65 (2H, m, —CH2), 2.74-2.75 (1H, m, —CH), 4.43-4.44 (2H, d, CH2), 6.39-6.43 (1H, d, ═CH), 7.05-7.07 (2H, d, Ar—H), 7.16-7.22 (4H, m, Ar—H), 7.29-7.32 (3H, m, Ar—H and ═CH), 7.40-7.44 (1H, d, ═CH), 7.49-7.51 (2H, d, Ar—H), 7.68-7.70 (2H, d, Ar—H), 7.89-7.90 (1H, d, —NH), 9.00 (2H, m, NH and OH), 10.73 (1H, s, NH), MS m/z: 498.1 (M+−1).
