M-Cresol → 4-Methoxy-3-(2-m-tolyloxy-acetyl)-benzoic acid methyl ester

Participants

Reaction Steps

The compound of step 1 (1.18 g, 4.12 mmol) and potassium carbonate (1.72 g, 12.4 mmol) were suspended in DMF (10 ml), m-cresol (450 mg, 4.12 mmol) was added, and the mixture was stirred at room temperature for 2 h. The volatiles were evaporated in vacuo, the residue was partitioned between EA and water, and the aqueous phase extracted with EA. The combined organic extracts were washed with a sodium chloride solution, dried over sodium sulfate, filtered and evaporated to dryness. The residue was purified by preparative RP HPLC (water/ACN gradient) to give 0.49 g of the title compound.
