Reaction Steps

2-(4-Chloro-phenoxy)-2-methyl-propionic acid (0.124 g, 0.58 mmol) and triethylamine (0.09 mL, 0.62 mmol) were combined in CH2Cl2 (2 mL) and cooled to 0° C. Oxalyl chloride (0.05 mL, 0.62 mmol) was added, followed by DMF (3 drops), and the mixture was slowly warmed to room temperature and stirred for 2 hours to give the title compound, which was used directly in the next step.
