Dimethyl Sulfoxide → 1-{4-[8-(1-methyl-1H-pyrazol-4-yl)-[1,2,4]triazolo[1,5-a]pyrazin-2-ylamino]-phenyl}-cyclopropanecarboxylic acid amide

Participants

Reaction Steps

1-{4-[8-(1-Methyl-1H-pyrazol-4-yl)-[1,2,4]triazolo[1,5-a]pyrazin-2-ylamino]-phenyl}-cyclopropanecarbonitrile is dissolved in methanol before potassiumcarbonate (5 eq.), DMSO (3.5 eq) and hydrogeneperoxide (30% solution, 5.eq) are added. The mixture is stirred for 5 h and monitored via LCMS MS. DMSO (3.5 eq) and hydrogeneperoxide (30% solution, 5.eq) ares added and the mixture iss stirred at rt for 16 h. The mixture is concentrated and the crude material purified via column chromatographie. LCMS purity (Method D): 100%, Rt: 1.70 min, observed [M+H]=375.1;
