Following the procedure as described in Example 21, making variation only as required to use 2-(chloromethyl)-5-(4-chlorophenyl)-1,3,4-oxadiazole 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 32% yield: 1H NMR (300 MHz, DMSO-d6) δ 8.80 (t, J=5.8 Hz, 1H), 8.65 (d, J=7.8 Hz, 1H), 8.0 (d, J=8.6 Hz, 2H), 7.66 (d, J=8.5 Hz, 2H), 7.32-7.19 (m, 5H), 6.46-6.39 (m, 2H), 5.60 (s, 2H), 4.38 (d, J=5.8 Hz, 2H), 2.54 (s, 3H); MS (ES+) m/z 534.1 (M+1).
