Procedure

Following the procedure as described in Example 4, making variations only as required to use 4-chlorophenyl isocyanate in place of phenyl isocyanate to react with 2-amino-4-methylthiazole-5-carboxylic acid benzylamide, the title compound was obtained as a white solid in 62% yield; m.p.>300° C.; 1H NMR (DMSO-d6, 300 MHz) δ 9.14 (s 1H), 8.47 (t, J=6.0 Hz, 1H), 7.51-7.48 (m, 2H), 7.35-7.17 (m, 8H), 4.35 (d, J=5.7 Hz, 2H), 2.43 (s, 3H); 13C NMR (DMSO-d6, 75 MHz) δ 162.2, 140.1, 138.1, 129.2, 128.7, 127.7, 127.1, 126.8, 120.7, 43.0, 39.1; MS (ES+) m/z 401.0 (M+1).
