Procedure

To a solution of 4-nitrophenol (3.00 g, 21.6 mmol) and K2CO3 (6.00 g, 43.4 mmol) in DMF (50 mL), t-butyl bromoacetate (2.90 mL, 19.6 mmol) was added. The mixture was stirred at room temperature for 5 h. Water and EtOAc were added. The organic phase was separated, washed with water, then with aq. 1N NaOH and brine. It was dried over Na2SO4, concentrated in vacuo to give tert-butyl 2-(4-nitrophenoxy)acetate as a solid.
