Following the procedure as described in Example 2, making variations only as required to use 3,5-dichlorobenzoyl chloride in place of benzoyl chloride to react with 2-amino-4-methylthiazole-5-carboxylic acid benzylamide, the title compound was obtained as a white solid in 34% yield; m.p. 104-105° C.; 1H NMR (CDCl3, 300 MHz) δ 7.69 (d, J=1.9 Hz, 2H), 7.52 (t, J=1.9, 1H), 7.35-7.31 (m, 5H), 6.04 (t, J=5.6 Hz, 1H), 4.59 (d, J=5.6 Hz, 2H), 2.44 (s, 3H); MS (ES+) m/z 420 (M+1).
