6 h at room temperature. The progress of reaction was monitored
by the consumption of aryl halide. The organic layer was collected
and the aqueous layer was washed with chloroform (3 ¥ 25 ml).
The combined organic layer is dried over anhydrous Na2SO4 and
solvent was evaporated at reduced pressure. Products were purified
either by crystallizing or by flash chromatography.
