実験手順

Oxalyl chloride (5.1 mL, 58 mmol) was added to a 0-5° C. solution of 2,2-dimethyl-4-pentenoic acid (5.00 g, 39.0 mmol) in 25 mL of dichloromethane. The mixture was stirred for 3 h, then concentrated to afford crude 2,2-dimethyl-4-pentenoyl chloride, which was dissolved in 10 mL of dichloromethane for use in the next step.
