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 (1-methyl-1H-imidazol-5-yl)methanamine, the title compound was obtained as a colorless solid in 75% yield: 1H NMR (300 MHz, CDCl3) δ 7.48 (s, 1H), 7.30-7.22 (m, 2H), 7.08-6.98 (m, 3H), 6.08 (s, 1H), 5.86 (t, J=5.0 Hz, 1H), 4.59 (d, J=5.0 Hz, 2H), 4.42 (s, 2H), 3.84-3.75 (m, 2H), 3.65 (s, 3H), 3.49-3.40 (m, 2H), 2.48 (s, 3H); MS (ES+) m/z 428.2 (M+1).
