실험 절차

To a solution of 2,2-dimethyltetrahydro-2H-pyran-4-carboxylic acid (530 mg, 3.35 mmol) in 10 mL of DCM at 0° C. was added 1 drop of DMF followed by oxalyl chloride (0.33 mL, 3.69 mmol) and the reaction stirred at RT for 3 hrs. The reaction was then concentrated and used with out further purification.
