Following the procedure as described in Example 21, making variation only as required to use 4-(chloromethyl)-3,5-dimethylisoxazole in place of 2-(chloromethyl)-5-phenyl-1,3,4-oxadiazole to react with N-benzyl-2-(4-hydroxy-2-oxopyridin-1(2H)-yl)-4-methylthiazole-5-carboxamide, the title compound was obtained as a colorless solid in 10% yield: 1H NMR (300 MHz, CDCl3) δ 8.69 (d, J=8.1 Hz, 1H), 7.41-7.26 (m, 5H), 6.16-6.06 (m, 3H), 4.76 (s, 2H), 4.59 (d, J=5.5 Hz, 2H), 2.68 (s, 3H), 2.41 (s, 3H), 2.27 (s, 3H); MS (ES+) m/z 451.1 (M+1).
