Dimethylformamide → (3,4-Diethoxy-phenyl)-acetyl chloride

Participants

Reaction Conditions

Reaction Steps

To a solution of (3,4-diethoxy-phenyl)-acetic acid (2.0 g, 8.9 mmol) in DCM (6 ml) were successively added oxalylchloride (1.13 ml, 13.4 mmol) and a catalytic amount of DMF (0.069 ml, 0.89 mmol) at 0° C. (ice bath). The reaction mixture was stirred at 0° C. for 1 h then evaporated to dryness under vacuum to yield the crude (3,4-diethoxy-phenyl)-acetyl chloride (2.2 g, 8.9 mmol, quant.) as a brownish oil which was used in the next step without further purification.
