A mixture of (R)-1-(3-methyl-4-(2-(3-methyl-1-tosyl-1H-indol-4-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-4-yl)piperazin-1-yl)ethanone (0.155 g, 0.278 mmol), 2-methyl-5-(3-methyloxetan-3-yl)phenyl trifluoromethanesulfonate (0.086 g, 0.278 mmol) prepared as described in Example 13, cesium carbonate (0.272 g, 0.834 mmol) and chloro(2-dicyclohexylphosphino-2′-4′-6′-triisopropyl-1,1′-biphenyl)[2-(2-aminoethyl)phenyl]palladium(II)-methyl-t-butylether adduct (CAS#1028276-56-5) (0.031 g, 0.042 mmol) in THF (4 mL) was heated in a microwave reactor at 140° C. for 3 h. The reaction was then filtered and concentrated, the resulting residue was purified by FCC (60-100% EtOAc/DCM) to provide (R)-1-(3-methyl-4-(2-(3-methyl-1-tosyl-1H-indol-4-yl)-6-(2-methyl-5-(3-methyloxetan-3-yl)phenyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-4-yl)piperazin-1-yl)ethanone. MS (ESI+) m/z 719.3 (M+H)+.
