Reaction Steps
To a suspension of 2-methyl-5-phenyl-1,3-thiazole-4-carboxylic acid (1.47 g, 6.70 mmol) in CH2Cl2 (30 mL) cooled at 0° C. was added DMF (26 μL, 0.34 mmol) and oxalyl chloride (0.73 mL, 8.38 mmol). The reaction was allowed to warm to ambient temperature and stirred for 4 h. The solution was concentrated in vacuo to provide 2-methyl-5-phenyl-1,3-thiazole-4-carbonyl chloride as a yellow-orange oil which gave a mass ion (ES+) of 236.3. 1H NMR δ (ppm) (CDCl3): 7.42-7.46 (5H, m), 2.78 (3H, s).
