Participants

Reaction Steps

To a solution of 4-[2-(4-chlorophenyl)-5-ethylthiazol-4-yl]-2,2,6,6-tetramethylpyran-3,5-dione (49 mg, 0.125 mmol) in dichloromethane (2 ml) is added triethylamine (87 μl, 0.625 mmol), followed by pivaloyl chloride (78 μl, 0.625 mmol), and the reaction mixture is stirred at room temperature for 17 hours. The reaction mixture is purified by flash chromatography on silica gel to give 2,2-dimethylpropionic acid 4-[2-(4-chlorophenyl)-5-ethylthiazol-4-yl]-2,2,6,6-tetramethyl-5-oxo-5,6-dihydro-2H-pyran-3-yl ester.
