Reaction Steps
To a solution of ethyl 4-hydroxybenzoate (15.3 g) in N,N-dimethylformamide (150 mL) is added successively 2-dimethylaminoethyl chloride hydrochloride (15.9 g) and potassium carbonate (43.2 g) and the mixture is stirred at 110° C. overnight. To the reaction mixture is added water and the mixture is extracted with ethyl acetate. The organic layer is washed successively with a saturated sodium hydrogencarbonate solution and water, dried over anhydrous sodium sulfate, and concentrated in vacuo. The resultant crude product is purified by flash column chromatography on silica gel (Solvent; chloroform:methanol=10:1) to give ethyl 4-[2-(dimethylamino)ethoxy]benzoate (14.1 g, yield; 65%) as a brown oil.
