23 mg (0.10 mmol) (S)—N-{1-[4-(3-Hydroxy-azetidin-1-yl)-phenyl]ethyl}-acetamide (V.1) in 1,4-dioxane (2.0 mL) is added to 31 mg (0.12 mmol) 1-[(6-bromo-pyridin-2-yl)-methyl-amino]-2-methyl-propan-2-ol. 38 mg (0.40 mmol) NaOtBu is added followed by 7.4 mg (0.01 mmol) chloro(2-dicyclohexylphosphino-2′,4′,6′-triisopropyl-1,1′-biphenyl)[2-(2-aminoethyl)phenyl]palladium(II). The mixture is stirred for 12 h at 50° C. 7.8 mg (0.01 mmol) chloro(2-dicyclohexylphosphino-2′,4′,6′-triisoporpyl-1,1′-biphenyl)[2-(2′-amino-1,1′-biphenyl)]palladium(II) is added and the mixture is stirred for 12 h at 100° C. After cooling to room temperature water (0.5 mL) and DMF (2.0 mL) are added and the mixture is filtered and concentrated. The residue is purified by HPLC (acetonitrile/water (+0.1% NH4OH)) to yield the desired product.
