2.22 g | With potassium carbonate; In N,N-dimethyl-formamide; at 70℃; for 1h;Inert atmosphere; | To a stirred mixture of 1, 2-dimethyl 4-hydroxyphthalate (2 g, 9.52 mmol, 1.0 equiv) and K2CO3 (2.64 g, 19.1 mmol, 2.0 equiv) in DML (30 ml), was added 2-(2- bromoethoxy)ethanol (5 g, 29.6 mmol, 3.1 equiv) under nitrogen atmosphere. The reaction mixture was stirred for 1 hr at 70 C in an oil bath, and then cooled to room temperature. The reaction was quenched by the addition of water (100 mL). The resulting mixture was extracted with EtOAc (3 x 150 mL). The combined organic layers were washed with brine (4 x lOOml), dried over anhydrous Na2S04. After filtration, the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography, eluting with EtOAc/ petroleum ether (0:1 to 3:2) to afford 1, 2-dimethyl 4-[2-(2-hydroxyethoxy)ethoxy]phthalate (2.22 g) as a light yellow oil. |
