Reaktionsschritte

5-Methanesulfonyl-2,3-dihydro-1H-indole (79 mg, 0.4 mmol) was dissolved in dioxane (2 mL). 2,4-Dichloro-[1,3,5]-triazine (60 mg, 1 eq), palladium acetate (11 mg, 5% molar), (+/−)binap (15 mg, 8% molar) and cesium carbonate (131 mg, 1 eq) were added and the reaction mixture was heated at 100° C. for 4 h. The mixture was cooled to room temperature and water was added. The mixture was filtered through celite and washed three times with dioxane. The collected filtrate was evaporated to dryness to give 11a (104 mg) which was used for the next step without further purification.
