Reaktionsschritte

To a suspension of 6-[6-(1H-pyrazol-4-yl)-[1,2,3]triazolo[4,5-b]pyrazin-1-ylmethyl]-quinoline (50 mg, 0.15 mmol) and Cs2CO3 (50 mg, 0.15 mmol) in DMF (2 mL) was added 2,2-dimethyl-oxirane. The reaction was stirred at 80° C. for 16 hours. The reaction was then purified with a reverse-phased preparative HPLC eluting with acetonitrile-water having 0.1% acetic acid to yield 2-methyl-1-[4-(3-quinolin-6-ylmethyl-3H-[1,2,3]triazolo[4,5-b]pyrazin-5-yl)-pyrazol-1-yl]-propan-2-ol (13 mg, 22% yield).
