実験手順

A microwave vial containing 5-(1-benzyl-1H-pyrazol-4-yl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (6.42 g, 22.1 mmol), 1-(2-(4-bromophenoxy)ethyl)pyrrolidine (5.1 mL, 24.3 mmol), tris(dibenzylideneacetone)dipalladium (0.633 g, 1.11 mmol), xantphos (1.28 g, 2.22 mmol), sodium tert-butoxide (4.34 g, 44.2 mmol) and 1,4-dioxane (50 mL) was heated under microwave irradiation (130° C., 15 min). Dimethylacetamide (2.5 mL) was added to assist with microwave absorption. The volatiles were removed under rotary evaporation, and the residue partitioned between ethyl acetate and water. The aqueous phase was extracted with ethyl acetate and the combined organics washed with water followed by brine. The organic phase was dried over magnesium sulfate, concentrated in vacuo and after trituration with the minimum amount of dichloromethane in diethylether afforded a pale yellow solid. Yield: 8.12 g, 77%; LCMS method: 2, RT: 2.52 min, MI: 480 [M+1].
