Oxalyl chloride → 3,4-Difluorophenylacetyl chloride

Participants

Reaction Steps

To a solution of 3,4-difluorophenylacetic acid (10.24 g, 60.4 mmol) in tetrahydrofuran (200 mL) and dimethylformamide (5 drops) at room temperature was added in 1 mL portions oxalyl chloride (11 mL, 126 mmol). The reaction mixture was stirred 2 hours at room temperature and concentrated to an orange liquid that was used directly in the next step.
