YieldReaction ConditionsOperation in experiment
84% With 1-butyl-3-methylimidazolium hydrogen sulfate; at 70℃; for 2h;Green chemistry; General procedure: General procedure for the synthesis of thiochromeno[3,4-d]pyrimidine (4): A dry 50 mL flask was charged with thiochroman-4-one 1 (1 mmol), aromatic aldehyde 2 a-n (1 mmol), thiourea 3 and [Bmim]HSO4 ionic liquid (2 mL). The reaction mixture was stirred at 70 C for 1 h. The progress of the reaction was monitored by TLC (eluent = n-hexane/ethyl acetate: 8/2, v/v). After completion of the reaction, the reaction mixture was cooled to RT and poured into ice cold water, the solid separated was filtered, washed with water, dried and purified by column chromatography using silica gel (ethyl acetate/n-hexane: 2/8, v/v) to afford title compounds 4a-n in good yields.
