Thiazolidinedione → HCID 58312813, 화합물

Crude 2-chloro-6-(2-methoxyethoxy)pyrimidine-4-carbaldehyde (sad105-052, 41.9 mg) was dissolved in ethanol (1.5 mL) and was added to a 10 mL vial containing the thiazolidine-dione (21.3 mg, 0.18 mmol) and the 1-(p-tolyl)piperazine (39.3 mg, 0.18 mmol). The reaction mixture was shaken at 80° C. for 15.5 h. LC-MS showed a peak with the desired mass at 2.18 min (M+1=456). The solvent was concentrated under reduced pressure and the residue was dissolved in EtOAc (20 mL) and washed with saturated NaHCO3 (10 mL). The organic layer was dried over Na2SO4 and concentrated under reduced pressure to provide 85.7 mg of brown oil. Purification by flash chromatography (SiO2,10 g, Hexanes/EtOAc 9:1 to 6:4 to 1:1) provided 11.5 mg (13.9% 2 steps, 83 mg theoretical) of pure (Z)-5-((6-(2-methoxyethoxy)-2-(4-(p-tolyl)piperazin-1-yl)pyrimidin-4-yl)methylene)thiazolidine-2,4-dione as a yellow solid.
