Reaction Steps

A suspension of (E)-2-(4,6difluoro-1-indanylidene)acetic Acid (5.49 g, 0.026 mol) in a mixture of dichloromethane: dimethylformamide (50 mL: 5 drops) was treated with oxalyl chloride (6.6 g 0.052 mol, Aldrich) and allowed to stir at ambient temperature for 18 h. The resulting solution was concentrated in vacuo and the residue used without further purification.
