The suspension was heated while stirring in a sealedtube under an argon atmosphere at 100 C for 2-6 h. The reactionwas checked by TLC using mobile phase toluene-ethylacetate (1:1,v/v). After the completion of the reaction, the reaction mixture wascooled to room temperature and evaporated under reduced pressure.The residue was partitioned between water (50 mL) and dichloromethane (50 mL), and the water phase was extracted twoadditional times with the same volume of dichloromethane. Thecombined organic phases were washed with water and brine andevaporated under reduced pressure. The crude product was crystallizedfrom petroleum ether/ethylacetate (3:1).
