The mixture was stirred at room temperature for 12 hours. The reaction mixture was diluted with chloroform (50 mL) and washed with water (2×50 mL). The organic layer was dried over anhydrous sodium sulfate, concentrated and the crude product obtained was crystallized from chloroform:petroleum ether (1:2) to obtain the title compound.
