Following the procedure as described in Example 22, making variation only as required to use (5-methylthiophen-2-yl)methanamine in replace of benzo[b]thiophen-2-ylmethanamine to react with 2-(4-(benzyloxy)-2-oxopyridin-1(2H)-yl)-4-methylthiazole-5-carboxylic acid, the title compound was obtained as a colorless solid in 43% yield: 1H NMR (300 MHz, DMSO-d6) δ 8.82 (t, J=5.8 Hz, 1H), 8.60 (d, J=8.1 Hz, 1H), 7.45-7.30 (m, 5H), 6.73 (d, J=3.3 Hz, 1H), 7.59-6.57 (m, 1H), 6.38 (dd, J=8.1, 2.7 Hz, 1H), 6.22 (d, J=2.7 Hz, 1H), 5.16 (s, 2H), 4.43 (d, J=5.8 Hz, 2H), 2.53 (s, 3H), 2.34 (s, 3H); MS (ES+) m/z 452.1 (M+1).
