The obtained mixture was refluxed for 4 hours, followed by the addition of water. The obtained mixture was extracted with chloroform thrice. The chloroform layers were combined, dried over magnesium sulfate and distilled under a reduced pressure to remove the solvent. The residue was recrystallized (from ethanol/ethyl acetate/hexane) to give 1.167 g of the title compound.
