Procedure
To the solution of 2-hydroxy-4-methoxybenzaldehyde 10 (6.6 mmol, 1 equiv.) and 2-iodopropane (7.23 mmol, 1.1 equiv.) in 7 mL of DMF was added K2CO3 (26.3 mmol, 4 equiv.). The reaction was stirred at 45° C. for 18 h. Next day, added DCM 5 mL, filtered off solid, and washed solid with DCM twice. The filtrate was washed by water. And then organic layer was dried over MgSO4, and concentrated. The remaining residues was purified by Biotage SP1:0-20% EtOAc in hexane over 7 CV, 20% EtOAc in hexane over 5 CV.
