Procedure
TMS-diazomethane (2.0 M in diethyl ether, 2.2 ml, 4.4 mmol) was added dropwise to a solution of 3-chlorocyclobutanecarboxylic acid (540 mg, 4.0 mmol) in methanol (5.0 mL) and dichloromethane (5.0 mL) at 0° C. The reaction mixture was concentrated under reduced pressure to afford methyl 3-chlorocyclobutanecarboxylate. The material was used in the subsequent reaction without purification.
