Participants

Reaction Steps

To a suspension of 4-(3-(cyclopropylamino)-2-(4-methylphenyl)-3-oxoprop-1-en-1-yl)benzoic acid (0.2 g, 0.6 mmol, prepared according to the procedure described in Example 99, step I-III) in DMF (3 mL) EDCl (0.23 g, 1.1 mmol), HOBt (0.08 g, 5 mmol), o-phenylenediamine (0.08 g, 0.7 mmol), were added followed by TEA (0.23 mL, 15 mmol). The reaction mixture was stirred for 4 hours after which the mixture was added to cold water (100 mL) and kept 0° C. for 1 hour to obtain a pale yellow solid. The solid was filtered and washed with water (50 mL) dried under vacuum to afford the title compound (0.110 g, 45% yield). 1H NMR (DMSO-d6) δ (ppm): 0.51 (2H, m, —CH2), 0.63-0.65 (2H, m, —CH2), 2.33 (3H, s, —CH3), 2.67-2.75 (1H, m, —CH), 4.87 (2H, s, —NH2), 6.55-6.58 (1H, m, Ar—H), 6.74-6.76 (1H, m, Ar—H), 6.93-6.97 (1H, m, Ar—H), 7.04 (2H, d, Ar—H), 7.11 (3H, m, Ar—H), 7.19 (2H, m, Ar—H), 7.25 (1H, s, ═CH), 7.76-7.78 (3H, m, Ar—H and —NH), 9.57 (1H, s, —NH), MS m/z: 412.2 (M++1).
