Versuchsvorschrift
1-((6-fluoropyridin-2-yl)methyl)-N-(1-methyl-1H-pyrazol-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-amine (Example 170) (45 mg, 0.138 mmol) was dissolved in DMF (0.6 ml) in a microwave tube under Nitrogen. This was sealed and heated at 180° C. for 1 h. The mixture was concentrated and purified by prep HPLC to afford 1-46-(dimethylamino)pyridin-2-yl)methyl)-N-(1-methyl-1H-pyrazol-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-amine as yellowish solid (20 mg, 42% yield). 1H NMR (d6-Acetone) δ 8.88 (s and br s, 2H), 8.06 (s, 1H), 7.99 (s, 1H), 7.61 (s, 1H), 7.40 (t, 1H), 6.49 (d, 1H), 6.24 (br s, 1H), 5.51 (s, 2H), 3.83 (s, 3H), 3.02 (s, 6H); LC-MS method B, (ES+) 350.1, RT=5.06 min.
