2-Methoxy-5-methylbenzaldehyde Use and Manufacturing
Stepi : 2-hydroxy-5-methylbenzaldehyde [613-84-3] was suspended in 5ml of dichloromethane and 5 ml of water. 1.47 ml (4.4 mmol, 3 eq.) of sodium hydroxide 1 N and 1.52 g (2.94 mmol, 2 eq.) of tetrabutyl ammonium hydroxide 50percent, then iodomethane (457 μl, 5 eq.) were added to the solution. The mixture was stirred 3h at room temperature. The reaction mixture was extracted 3 times with dichloromethane, the combined organic layers were washed with brine, dried with anhydrous MgSOGeneral procedure: To a solution of the hydroxy-methylbenzaldehyde (34 mg, 0.25 mmol) in anhydrous DMF (6.0 mL), K2CO3 (35 mg, 0.25 mmol) was added and the mixture was stirred at room temperaturefor 30 minutes. Then, methyl iodide (30 μL, 68 mg, 0.5 mmol) was added and the reaction was stirred at room temperatureovernight. The reaction was quenched by the additionof distilled water, and the aqueous phase was extracted threetimes with ethyl acetate. The combined organic phases weredried with MgSO4 and concentrated in vacuo. The residue waspurified by column chromatography on silica gel.
