실험 절차

A mixture of 2-methylhydrocinnamic acid (3.0 g, 18.3 mmole), oxalyl chloride (3.19 ml, 36.6 mmole) and methylene chloride (30 ml) was cooled in an ice bath and N,N-dimethylformamide (0.14 ml, 1.81 mmole) was added dropwise. The mixture was stirred at room temperature overnight. Concentration in vacuo gave 3-(2-methylphenyl)propanoyl chloride which was taken up in methylene chloride and used in the next step as a crude.
