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]thiazol-2-ylmethanamine, the title compound was obtained as a colorless solid in 81% yield: 1H NMR (300 MHz, CDCl3) δ 8.00 (d, J=8.0 Hz, 1H), 7.85 (d, J=8.0 Hz, 1H), 7.51-7.44 (m, 1H), 7.41-7.34 (m, 1H), 7.31-7.24 (m, 2H), 7.07-6.98 (m, 2H), 6.63 (t, J=5.5 Hz, 1H), 6.13 (s, 1H), 5.01 (d, J=5.5 Hz, 2H), 4.44 (s, 2H), 3.84-3.76 (m, 2H), 3.48-3.40 (m, 2H), 2.53 (s, 3H); MS (ES+) m/z 481.2 (M+1).
