To this solution was slowly added choroacetyl chloride and the reaction mixture was allowed to cool to room temperature overnight. The solution was concentrated and the resulting solid was extracted with ethyl acetate. The organic extract was first washed with 10% HCl (2×2 ml), then with water (12×25 ml) and was collected, dried and evaporated to obtain the title compound (yield, 10.2 g). 1HNMR (250 MHz, CDCl3): 4.22 (s, 2 H), 7.26 (d, J=8 Hz, 1 H), 7.66 (d, J=8 Hz, 1 Hz), 8.68 (s, 1 H), 9.02 (br s, 1 H).
