Procedure

To a solution of 4-isopropoxy-3-methyl-benzoic acid (1.35 g, 6.95 mmol) in chloroform (20 mL), thionylchloride (2.48 g, 20.9 mmol) is added. The mixture is refluxed for 2 h before the solvents are removed in vacuo to give crude 4-isopropoxy-3-methyl-benzoic acid chloride; LC-MS: tR=1.00 min.
