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 (5-methylfuran-2-yl)methanamine, the title compound was obtained as a yellowish solid in 78% yield: 1H NMR (300 MHz, CDCl3) δ 7.30-7.23 (m, 2H), 7.08-6.98 (m, 2H), 6.12 (d, J=2.4 Hz, 1H), 6.07 (s, 1H), 5.93 (t, J=4.8 Hz, 1H), 5.89 (d, J=2.4 Hz, 1H), 4.49 (d, J=4.8 Hz, 2H), 4.42 (s, 2H), 3.83-3.74 (m, 2H), 3.49-3.39 (m, 2H), 2.48 (s, 3H), 2.27 (s, 3H); MS (ES+) m/z 450.1 (M+23).
