YieldReaction ConditionsOperation in experiment
General procedure: The syntheses of compounds 4a-4h were mainly referred to literature method [41]. A mixture of semicarbazide hydrochloride (2g, 17.9mmol) and anhydrous CH3COONa (2g, 24.4mmol) in EtOH (20mL) was refluxed for 45min and filtered while hot. 10a-10h (16.6mmol) was added to the filtrate, and the mixture was refluxed for 1h. The mixture was stirred at room temperature for an additional 10h, and the precipitate that formed was filtered and dried to afford 11a-11h. POCl3 (3.6mL, 39mmol) was added dropwise to dry DMF (8.4mL, 108mmol) in ice bath, and the mixture was stirred at 0C for 1h, followed by the addition of 11a-11h (17mmol) in small portions. The mixture was heated at 80C for 1.5h and quickly poured onto ice (100mL), then treated with 30% aqueous NaOH to adjust pH=8-9, stirred for 30min and neutralized with conc. HCl. After stirred at room temperature for additional 18h, the resulting precipitate was filtered, washed with water, recrystallized from water and dried to afford 4a-4h.
