YieldReaction ConditionsOperation in experiment
42 g With potassium carbonate; In acetone; for 20h;Reflux; To a solution of <strong>[19676-64-3]2,3,4-trimethoxyphenol</strong> (71g, 0.38mol), K2CO3 (50g, 0.36mol) in acetone (400mL) at room temperature was added dimethvl sulfate (53g, 0.42mol) in 15min. The reaction mixture was stirred and refluxed for 20h, and the solvent was evaporated followed by the addition of water (400mL). The mixture was simply stirred for 15min and allowed to stand at room temperature for 4h. The crude crystalline product formed and was collected, washed with water and purified by recrystallization from MeOH to afford 1,2,3,4-tetramethoxybenzene 45 (42g) as white solid. Total yield (from step 1 to 3): 70.6%. Mp 85.8-86.1C (lit [70]. mp 87-87.5C). TLC: Rf=0.75 (1:5 EtOAc/hexanes). 1H NMR (600MHz, Chloroform-d) δ 6.58 (s, 2H), 3.90 (s, 6H), 3.82 (s, 6H). 13C NMR (151MHz, Chloroform-d) δ 147.91, 143.52, 106.53, 61.33, 56.52. HRMS (+ESI) 199.0968 [M+ H]+, 221.0788 [M+ Na]+ (calcd. for C10H15O4+ 199.0965 and C10H14O4Na+ 221.0784).
