Reaction Steps
To a stirred solution of 3-methyl-2-phenylvaleric acid (1.23 g; 6.2 mmol) and a catalytic amount of dry dimethylformamide (ca. 20 μL) in 5 mL of dry methylene chloride under nitrogen at room temperature was added oxalyl chloride (4.8 mL of 2.0 M solution in methylene chloride) dropwise. After 45 minutes, the mixture was concentrated in vacuo and used immediately for Step 2.
