Participants

Reaction Steps

Similar reaction of 2-iodoisophthalic acid and 2-isopropylaniline gave 2-[(2-isopropyl)phenylamino]-isophthalic acid (38%), mp (EtOAc/petroleum ether) 217-219° C. 1H NMR [(CD3)2SO] δ 1.25 (d, J=6.8 Hz, 6 H, 2×CH3), 3.22-3.29 (m, 1 H, CH), 6.81 (dd, J=7.4, 1.8 Hz, 1 H, H-3' or H-6'), 6.93 (t, J=7.7 Hz, 1 H, H-2), 6.92-7.02 (m, 2 H, H-4' and H-5'), 7.26 (dd, J=7.1, 2.2 Hz, 1 H, H-6' or H-3'), 7.90 (d, J=7.7 Hz, 2 H, H-4 and H-6), 9.69 (s, 1 H, NH), 12.93 (br s, 2 H, 2×COOH).
