反応手順
Benzoyl chloride (0.04 mL, 0.36 mmol) was added to a mixture of 2-amino-4-methylthiazole-5-carboxylic acid benzylamide (0.083 g, 0.033 mmol), 4-dimethylamino-pyridine (10 mg) and triethylamine (0.06 mL, 0.43 mmol) in tetrahydrofuran (10 mL) at 0° C. The reaction mixture was stirred at ambient temperature for 8 h, then concentrated. The residue was purified by column chromatography to afford the title compound in 75% yield (87 mg); 1H NMR (CDCl3, 300 MHz) δ 7.90-7.24 (m, 11H), 5.97 (s, br, 1H), 4.59 (d, J=5.8 Hz, 2H), 2.45 (s, 3H); MS (ES+) m/z 352.0 (M+1).
