실험 절차

Cesium carbonate (2.55 g, 7.82 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (0.301 g, 0.52 mmol) and diacetoxypalladium (0.058 g, 0.26 mmol) were added to a stirred suspension of 3-(2-chloro-5-methylpyrimidin-4-yl)-1-(phenylsulfonyl)-1H-indole (2 g, 5.21 mmol) and 1-(4-(4-amino-3-methoxyphenyl)piperazin-1-yl)ethanone (1.299 g, 5.21 mmol) in 1,4-dioxane (50 ml). The resulting suspension was degassed with argon and stirred at 90 °C for 2 hours. After cooling, the mixture was filtered through a pad of Dicalite speed plus and washed with dichloromethane. The solvent were evaporated. PBO-01132-93-01 The crude product was purified by flash chromatography on silica gel (Merck cartrige SVP D40 - SI60 16-40µm - 90g) eluting with 0 up to 100% EtOAc in dichloromethane . The 1-(4-(3-methoxy-4-(5-methyl-4-(1-(phenylsulfonyl)-1H-indol-3-yl)pyrimidin-2-ylamino)phenyl)piperazin-1-yl)ethanone (1.760 g, 56.6 %) was obtained as a yellow oil. PBO-01132-93-02 An impure batch was obtained. PBO-01132-93-03
