Participants

Reaction Steps

4-(4-Methoxyphenyl)butyric acid (2.0 g, 10.3 mmol) was treated with thionyl chloride (20 mL). The reaction was stirred at rt for 3 h, heated at 65° C. overnight and then concentrated under reduced pressure to give 4-(4-methoxyphenyl)butyryl chloride (2.3 g) as a yellow oil which was used without farther purification.
