Following the procedure as described in Example 23, making variations as required to replace 4-(chloromethyl)benzonitrile with ethyl 4-(bromomethyl)benzoate to react with N-benzyl-4-methyl-2-(2-oxoimidazolidin-1-yl)thiazole-5-carboxamide, the title compound was obtained as a colorless solid in 20% yield: mp 118-120° C. (ethyl acetate/hexanes); 1H NMR (300 MHz, CDCl3) δ 8.01 (d, J=8.3 Hz, 2H), 7.35-7.27 (m, 7H), 5.88 (t, J=5.5 Hz, 1H), 4.56 (d, J=5.5 Hz, 2H), 4.51 (s, 2H), 4.36 (q, J=7.1 Hz, 2H), 4.10-4.05 (m, 2H), 3.47-3.42 (m, 2H), 2.60 (s, 3H), 1.37 (t, J=7.1 Hz, 3H); 13C NMR (75 MHz, CDCl3) δ 166.1, 162.3, 157.1, 155.4, 153.1, 140.5, 137.9, 130.3, 130.1, 128.8, 128.1, 127.8, 127.6, 117.3, 61.1, 47.7, 44.0, 42.0, 41.8, 17.2, 14.3; MS (ES+) m/z 479.4 (M+1).
