Cesium carbonate → HCID 90100619, compound

Participants

Reaction Steps

10.0 mg (1.0 eq) of the obtained tert-butyl 4-(4-(2-(3-fluorophenyl)-5-hydroxypyridin-4-yl)pyrimidin-2-yl)piperazin-1-carboxylate and 9.1 mg (1.0 eq) of the obtained tert-butyl((5-chloro-2,4-difluorophenyl)sulfonyl)(thiazol-4-yl)carbamate were dissolved in 0.2 mL of N,N-dimethylformamide 0.2 mL, then 21.6 mg (3.0 eq) of Cs2CO3 was added thereto. The mixture was reacted at room temperature for 16 hours. The solvent was removed by concentrating under reduced pressure. The residue was separated by PLC (developing solvent, hexane:ethyl acetate=2:1) to obtain 10 mg of tert-butyl 4-(4-(5-(4-(N-(tert-butoxycarbonyl)-N-(thiazol-4-yl)sulfamoyl)-2-chloro-5-fluorophenoxy)-2-(3-fluorophenyl)pyridin-4-yl)pyrimidin-2-yl)piperazin-1-carboxylate.
