反応手順
Sodium 4-{4-[4-(3-methanesulfonyl-propoxy)-indol-1-yl]-pyrimidin-2-ylamino}-cyclohexanecarboxylate (0.4 g), (R)-piperidine-3-carboxylic acid ethyl ester (0.165 g), BOP (0.537 g) and DIPEA (0.56 mL) were added to DMF (3 mL), and the mixture was stirred at room temperature overnight. The mixture was diluted with water and the resulting precipitate was collected by filtration, washed with water, dried under reduced pressure, and purified by flash chromatography (DCM/MeOH) to give 39.6 mg of (R)-1-(4-{4-[4-(3-methanesulfonyl-propoxy)-indol-1-yl]-pyrimidin-2-ylamino}-cyclohexanecarbonyl)-piperidine-3-carboxylic acid ethyl ester, MP=175.0-177.0° C.
