Reaction Steps

To a solution of 4-(3-(cyclopropylamino)-2-(4-fluorophenyl)prop-1-en-1-yl)benzoic acid (0.4 g, 1.3 mmol) in DMF (5 mL), EDCl (0.49 g, 2.6 mmol), HOBt (0.175 g. 1.3 mmol) and TEA (0.54 mL, 3.9 mmol), were added, followed by n-phenylenediamine (0.280 g, 2.6 mmol). The reaction mixture was stirred at room temperature for 2 hours, subsequently the residue was poured into water and extracted with ethyl acetate (300 mL) and washed with water (3×50 mL) and brine (100 mL). The organic layer was dried over anhydrous Na2SO4 and concentrated to afford the crude compound. The obtained compound was purified with flash chromatography using 15% ethyl acetate/hexane as the eluent, pure fraction evaporated to afford title compound (0.040 g, 9% yield). 1H NMR (DMSO-d6) δ (ppm): 0.24-0.25 (2H, m, —CH2), 0.37-0.39 (2H, m, —CH2), 2.13-2.14 (1H, m, —CH), 3.57 (2H, s, —CH2), 4.86 (2H, s, —NH2), 6.55-6.59 (1H, t, Ar—H), 6.70 (1H, s, ═CH), 6.74-6.76 (1H, d, Ar—H), 6.93-6.95 (1H, t, Ar—H), 7.02-7.04 (2H, m, Ar—H), 7.10-7.12 (1H, d, Ar—H), 7.16-7.26 (4H, m, Ar—H), 7.74-7.76 (2H, d, Ar—H), 9.52 (1H, s, —NH), MS m/z: 402.2 (M++1).
