실험 절차

According to GP1 tert-butyl 4-(2,4-dioxo-6-phenyl-1,4-dihydrothieno[3,2-d]pyrimidin-3(2H)-yl)piperidine-1-carboxylate (1 g; compound B50) is reacted with 5-(chloromethyl)-3-[(methylsulfanyl)methyl]-1,2,4-oxadiazole (410 mg; compound D11) in the presence of potassium carbonate (320 mg) in DMF (20 ml). The reaction mixture is stirred at 100° C. for 1 h. Ice cold water is added and the mixture is extracted with DCM 4 times. The combined organic layers are dried (sodium sulfate) and concentrated in vacuo. The residue is purified by flash column chromatography [silica gel, eluation gradient: cyclohexane/EtOAc, 1/0 to 1/1 (v/v)] to afford the title compound as a solid.
