A mixture of 5-iodovanillin (7 g, 25.18 mmole), potassium carbonate (8.78 g, 63.53 mmole) and iodomethane (6.43 g, 45.30 mmole) was suspended in 60 mL of DMF and stirred at room temperature for 14 hours. The reaction mixture was quenched with water and extracted with diethyl ether. The organic layer was dried over MgSO4, filtered and evaporated in vacuo to obtain a solid which was recrystallized from hexane/ethyl acetate (2:1) (6.28 g, 85.4%).
