Versuchsvorschrift

1,2-Dimethoxyethane (6.75 mL) was added to a 20 mL microwave vial containing a mixture of (R)-6-benzyl-2-chloro-4-(3-methyl-4-((2-nitrophenyl)sulfonyl)piperazin-1-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (1.1 g, 2.03 mmol) and 3-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-tosyl-1H-indole (0.92 g, 2.23 mmol). Then 2M aqueous Na2CO3 was added and the reaction mixture was degassed via three argon/vacuum cycles, then charged with Pd(Ph3P)4 (0.234 g, 0.203 mmol). The vial was sealed and heated via microwave irradiation at 140° C. for 90 minutes. The mixture was then cooled to room temperature and diluted with Et2O and water. The layers were separated and the aqueous layer was extracted two additional times with dichloromethane. The organic layers were combined dried over MgSO4, filtered and concentrated. The resulting residue was purified by silica gel flash chromatography [55-75% ethyl acetate (containing 2% EtOH)/heptanes] to afford (R)-6-benzyl-2-(3-methyl-1-tosyl-1H-indol-4-yl)-4-(3-methyl-4-((2-nitrophenyl)sulfonyl)piperazin-1-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine. MS (ESI+) m/z 792.5 (M+H)+.
