Procedure

A mixture of 2-methylanisole (30 g, 0.25 mol) and methacrylic acid (27 g, 0.31 mol) was added at 60° C. to a well stirred Eaton reagent (69 g P2O5 and 350 mL of methanesulfonic acid). After 30 min of stirring the reaction mixture was cooled, poured into ice water, and filtered. The residue was recrystallized from hexane/benzene (10:1). Yield=22 g (46%).
