実験手順
4-{5-[2-Amino-7-methyl-8-(3-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-6-yl]-pyrazol-1-yl}-benzonitrile (Ex. 1, 459 mg, 1 mmol), N,N-dimethylglycine (206 mg, 2 mmol), and triethylamine (0.278 mL, 2 mmol) were stirred in dry DMF (5 mL) and then HATU (760 mg, 2 mmol) was added portionwise. The reaction mixture was heated at 70° C. for 40 mins then a further quantity of HATU (760 mg, 2 mmol) was added and the mixture heated at 80° C. for 1 hr. The reaction mixture was allowed to cool and then partitioned between EtOAc and water. The organic layer was washed with water followed by brine, and then dried (Na2SO4), filtered and concentrated in vacuo. The resultant residue was treated with DCM, the suspension filtered and the filtrate purified by flash chromatography with a gradient of 0-10% MeOH in DCM to afford the title compound as a white solid (88 mg).
