Procedure

To a mixture of 4-(3 -chloropropoxy)-3-methoxybenzoic acid (2.4 g, 10 mmol) in dichloromethane (5 ml) was added thionyl chloride (0.9 ml, 12 mmol) dissolved in dichloromethane (5 ml). The reaction was stirred and refluxed for 1 hour, and then the dichloromethane was removed in vacuo to leave a dark oil. The oil was triturated with hexane and the solid that formed while scratching with a glass rod was collected to afford 1.6 g of 4-(3-chloropropoxy)-3-methoxybenzoyl chloride, m.p.=60-63° C.
