Potassium Carbonate → 2-(4-{2-[4-(2-Pyrrolidin-1-yl-ethoxy)-phenylamino]-[1,2,4]triazolo[1,5-a]pyridin-5-yl}-pyrazol-1-yl)-ethanol

Participants

Reaction Steps

To a stirred solution of [5-(1H-pyrazol-4-yl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-[4-(2-pyrrolidin-1-yl-ethoxy)-phenyl]-amine (0.40 g, 1.03 mmol) in dimethylformamide (10 ml) was added potassium carbonate (2 g) followed by 1-chloroethanol (140 μl, 2.06 mmol). The mixture was stirred for 18 hours at room temperature, then filtered and concentrated in vacuo to provide a yellow solid. No further purification was required. Yield: 0.45 g, 89%; LCMS method: 2, RT: 2.10 min, MI: 434 [M+1].
