実験手順
To a solution of 2,4-dichloro-thiazole-5-carboxylic acid (1.98 g, 10 mmol) in toluene (50 mL) was added Et3N (1.01 g, 10 mmol) followed by diphenyl phosphoryl azide (2.75 g, 10 mmol). The reaction mixture was stirred at room temperature for 20 h. The reaction mixture was concentrated in vacuo and purified by silica gel chromatography (0 to 100% ethyl acetate/hexanes) to afford product as a brown solid (1.82 g, 82%): 13C NMR (75 MHz, CDCl3) δ 163.33, 156.83, 143.94, 124.02.
