4-丁氧基-2,6-二甲基苯甲醛

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 1-Iodobutane (9.2 g; 50 mmole) and potassium carbonate (6.9 g; 50 mmole) were added to a solution of 2,6-dimethyl-4-hydroxybenzaldehyde (7.5 g; 50 mmole) in methyl ethyl ketone (150 ml). The mixture was heated under reflux with stirring for 20 hours and then evaporated to dryness. The residue was dissolved in dichloromethane and washed with water, then dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give 4-butoxy-2,6-dimethylbenzaldehyde (9.4 g; 92.0%). The product was obtained as a yellow oil and was characterized by its proton magnetic resonance spectrum, the details of which are recorded in Table 2 below.
