To a solution of 5-hydroxy indole (4.56 gm, 0.034 moles) in DMF (20 ml), potassium carbonate (9.43 gm, 0.068 moles), ethyl bromoacetate (6.29 gm, 0.0377 moles) were added and the reaction mixture was stirred at ambient temperature for 12 hours. The reaction mixture was poured into ice cold water and extracted with ethyl acetate. The combined ethyl acetate extract was washed with water & brine, dried over sodium sulphate and evapourated under reduced pressure to yield 6.2 gm (82%) of product as solid.
