Participants

Reaction Steps

Following the procedure as described in Example 1, making variations only as required to use 2-cyclopropylethylamine in place of benzylamine to react with 4-methyl-2-[(pyridine-4-carbonyl)amino]thiazole-5-carboxylic acid, the title compound was obtained as a white solid in 20% yield; 1H NMR (DMSO-d6, 300 MHz) δ 8.82-8.80 (m, 2H), 8.08-7.72 (m, 3H), 3.27-3.16 (m, 2H), 2.45 (s, 3H), 1.41-1.34 (m, 2H), 0.73-0.65 (m, 1H), 0.48-0.25 (m, 2H), 0.12-0.80 (m, 2H); MS (ES+) m/z 331.1 (M+1).
