Following the procedure as described in Example 2, making variations only as required to use 3-methanesulfonylbenzoyl 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 15% yield; m.p. 111-113° C.; 1H NMR (CD3OD, 300 MHz) δ 8.55 (t, J=5.8 Hz, 1H), 8.09 (dd, J=1.2, 7.6 Hz, 1H), 7.36-7.19 (m, 2H), 7.68 (dd, J=1.2, 7.6 Hz, 1H), 7.27 (m, 5H), 4.50 (d, J=1.9 Hz, 2H), 3.33 (s, 3H), 2.52 (s, 3H); MS (ES+) m/z 430.1 (M+1).
