Following the procedures as described in Example 55, making variations as required to replace 3-methyl-5-(2-oxo-3-(2-phenoxyethyl)imidazolidin-1-yl)thiophene-2-carboxylic acid with 5-(3-(4-fluorobenzyl)-2-oxoimidazolidin-1-yl)-3-methylthiophene-2-carboxylic acid to react with thiazol-2-ylmethanamine, the title compound was obtained as a colorless solid in 48% yield: 1H NMR (300 MHz, CDCl3) δ 7.72 (d, J=3.3 Hz, 1H), 7.31-7.23 (m, 3H), 7.07-6.99 (m, 2H), 6.50 (t, J=5.4 Hz, 1H), 6.12 (s, 1 H), 4.90 (d, J=5.4 Hz, 2H), 4.43 (s, 2H), 3.84-3.75 (m, 2H), 3.47-3.39 (m, 2H), 2.50 (s, 3H); MS (ES+) m/z 453.1 (M+23).
