反応手順

A solution of 2,2-dimethyl-3-phenylpropanoic acid (0.856 g, 4.8 mmol) in chloroform (6 mL) at 0° C. was treated with oxalyl chloride (3.05 g, 24 mmol) and 1 drop of dimethylformamide. The reaction solution was stirred for 1 h at 0° C. The ice bath was removed and the reaction mixture stirred at room temperature over night. The solvent was removed under reduced pressure and dried under high vacuum to afford a quantitative amount of 2,2-dimethyl-3-phenylpropanoyl chloride. The oil was directly used in the following reaction.
