Versuchsvorschrift

A mixture of 2-(1-((2-chloro-9-methyl-6-morpholino-9H-purin-8-yl)methyl)piperidin-4-yl)propan-2-ol (1.21 g, 2.96 mmol), benzene-1,2-diamine (520 mg, 4.8 mmol), palladium acetate (66 mg, 0.29 mmol), bist(tri-t-butylphosphine)palladium (150 mg, 0.29 mmol) and sodium tert-butoxide (620 mg, 6 4 mmol) in toluene (30 mL) was stirred at 95° C. for 18 hours. The reaction mixture was then filtered through paper and then concentrated. The crude product was then purified by flash chromatography using a Biotage KP-NH column (0-10% gradient MeOH in DCM) to give 2-(1-((2-(2-aminophenylamino)-9-methyl-6-morpholino-9H-purin-8-yl)methyl)piperidin-4-yl)propan-2-ol (1.2 g, 84%). LCMS: M+H+=481.2.
