실험 절차

To a solution of 4-{5-[7-methyl-3-oxo-8-(3-trifluoromethyl-phenyl)-2,3-dihydro-[1,2,4]triazolo[4,3-a]pyridin-6-yl]-pyrazol-1-yl}-benzonitrile (Ex. 9, 55 mg. 0.12 mmol) in DMF (3 mL) was added cesium carbonate (58 mg, 0.18 mmol) followed by 2-chloro-N,N-dimethylacetamide (19 μL, 0.18 mmol). The reaction mixture was stirred at RT for 18 hrs then water was added and the reaction mixture was extracted with EtOAc (2×20 mL). The combined organic extracts were dried (Na2SO4), filtered and evaporated in vacuo. The resultant residue was purified by preparative HPLC, eluting with a gradient of 20-70% MeCN in water (+0.1% formic acid) to give the title compound as a yellow solid (22 mg).
