Versuchsvorschrift

A mixture of 2-chloro-9-methyl-6-morpholin-4-yl-8-(4-oxetan-3-yl-piperidin-1-ylmethyl)-9H-purine (0.2 g, 0.49 mmol), benzene-1,2-diamine (0.106 g, 0.98 mmol), Xphos (0.047 g, 0.098 mmol), Pd2(dba)3 (0.022 g, 0.025 mmol) and Cs2CO3 (0.32 g, 0.98 mmol) in DMF (2 mL) was subjected to microwave irradiation at 150° C. for 30 min. The suspension was filtered through Celite and the solution was concentrated in vacuo. The residue was purified by flash chromatography (Si—PPC, MeOH:DCM, gradient 0:100 to 10:90) to give N-[9-Methyl-6-morpholin-4-yl-8-(4-oxetan-3-yl-piperidin-1-ylmethyl)-9H-purin-2-yl]benzene-1,2-diamine as yellow foam (0.117 g, 50%). LCMS (Method A): RT=2.14 min, [M+H]+ 479.2
