実験手順

1-(2-Propylsulfanyl-pyrimidin-4-yl)-1H-indol-4-ol (1.56 g) and toluene-4-sulfonic acid 1,1-dioxo-tetrahydro-1lambda*6*-thiophen-3-ylmethyl ester (2.37 g) were added to NMP (20 mL), followed by cesium carbonate (5.08 g). The mixture was stirred at 70° C. for 60 hours, after which solvent was removed by distillation. The residue was diluted with 1N HCl and extracted with EtOAc. The combined organic layers were washed with brine, dried (MgSO4), filtered and concentrated under reduced pressure to give 2.96 g of 4-(1,1-dioxo-tetrahydro-1lambda*6*-thiophen-3-ylmethoxy)-1-(2-propylsulfanyl-pyrimidin-4-yl)-1H-indole.
