Methyl tetraethylene glycol (1.0 g, 4.80 mmol) and tert-butyl acrylate (0.308 g, 2.40 mmol) were dissolved in dry THF (10 mL). Sodium metal 0.6 mg, 0.024 mmol) was added to the solution. After stirring for 4 h at room temperature, the reaction mixture was quenched by the addition of 1 M HCl (15 mL). The quenched reaction mixture was then extracted with CH2Cl2 (1×50 mL, 1×25 mL). The organic layer was dried (MgSO4) and concentrated. After purification by silica gel chromatography (ethyl acetate as eluent), the product was obtained as an oil (1.28 g, 79%).
