[8-(4-Methanesulfonyl-phenoxy)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-(1-(2-pyrrolidin-1-yl-ethyl)-1H-pyrazol-4-yl]-amine was synthesized from 2-chloro-8-(4-methanesulfonyl-phenoxy)-[1,2,4]triazolo[1,5-a]pyridine (0.100 g, 0.309 mmol) and 1-(2-pyrrolidin-1-yl-ethyl)-1H-pyrazol-4-ylamine (0.072 g, 0.402 mmol) in a manner analogous to Example 2d. The isolated pure product was treated with 2N hydrogen chloride in dioxane. [8-(4-Methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-(1-(2-pyrrolidin-1-yl-ethyl)-1H-pyrazol-4-yl]-amine hydrochloric acid salt was isolated as a tan solid (81 mg, 56%).
