The downstream synthesis method of this compound is introduced below.
Under inert gas atmosphere 0.80 g (2.53 mmol) of example XIII.1 , 0.65 g (2.53 mmol) of 2-chloro-4-iodo-3-methyl-pyridine, 1.00 g (10.4 mmol) NaOtBu and 100 mg (0.14 mmol) chloro(2-dicyclohexylphosphino-2’>4′,6′-triisopropyl-1 , 1 ‘-biphenyl)(2-(2- aminoethyl)-phenyl)-palladium (II) are added to 50 mL dioxane and stirred at 45 C over night. Afterwards the solvent is removed, water is added and the product is extracted with EtOAc. The organic layer is dried over MgS04, filtered and the solvent is removed in vacuo. The crude product is purified by HPLC (ACN/H20/TFA). C20H24CIN3O2 (M= 373.9 g/mol) ESI-MS: 374 [M+H]+ Rt (HPLC):0.77 min (method M)
