Participants

Reaction Steps

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 benzo[d][1,3]dioxol-5-ylmethanamine, the title compound was obtained as a colorless solid in 82% yield: 1H NMR (300 MHz, CDCl3) δ 7.30-7.23 (m, 2H), 7.07-6.98 (m, 2H), 6.85-6.73 (m, 3H), 6.09 (s, 1H), 5.95 (s, 2H), 5.92 (t, J=5.5 Hz, 1H), 4.46 (d, J=5.5 Hz, 2H), 4.42 (s, 2H), 3.84-3.76 (m, 2H), 3.48-3.40 (m, 2H), 2.49 (s, 3H); MS (ES+) m/z 468.2 (M+1).
