Trimethylsilyldiazomethane (2M/ether, 3.5 mL) was added slowly to a solution of 3,5-dichlorobenzoic acid (2-C) (955 mg, 5.0 mmol) in methylene chloride (5.0 mL) and methanol (2.0 mL) until the yellow color persisted. After stirring for 10 min, the mixture was evaporated in vacuo to give methyl 3,5-dichlorobenzoate (2-D).
