Procedure

Following the procedure as described in Example 10, making variations as required to replace cyclopropylmethyl bromide with cyclopentylmethyl 4-methylbenzenesulfonate to react with ethyl 4-methyl-2-(2-oxoimidazolidin-1-yl)thiazole-5-carboxylate, the title compound was obtained in 62% yield: 1H NMR (300 MHZ, CDCl3) δ 4.20 (q, J=7.2 Hz, 2H), 4.04-3.99 (m, 2H), 3.52-3.41 (m, 2H), 3.17 (d, J=7.5 Hz, 2H), 2.46 (s, 3H), 2.16-1.08 (m, 12H); MS (ES+) m/z 338.3 (M+1).
