Versuchsvorschrift

A mixture of 4-(2-chloro-8-((4-(2-methoxypropan-2-yl)piperidin-1-yl)methyl)-9-methyl-9H-purin-6-yl)morpholine (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 t-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 N1-(8-((4-(2-methoxypropan-2-yl)piperidin-1-yl)methyl)-9-methyl-6-morpholino-9H-purin-2-yl)benzene-1,2-diamine (1.2 g, 84%). LCMS: M+H+=481.2.
