実験手順

A solution of Intermediate 74d (0.51 g, 1.45 mmol) in xylene (2.4 mL) was treated with 3-(tert-butyl)-1H-pyrazol-5-amine (0.18 g, 1.32 mmol) then potassium carbonate (0.38 g, 2.76 mmol), trans-N,N′-Dimethyl-1,2-cyclohexanediamine (0.037 g, 0.26 mmol) and copper (I) iodide (0.013 g, 0.066 mmol) were added. The mixture was degassed then heated at 150° C. for 4 h using microwave irradiation. Another portion of copper (I) iodide (0.006 g, 0.03 mmol) was added and the reaction mixture heated at 150° C. for a further 2 h using microwave irradiation. The mixture was diluted with water (1 mL), conc. aqueous ammonium hydroxide (1 mL) and EtOAc (1 mL) and the phases separated. The aqueous layer was then extracted with EtOAc (2×). The combined organic layers were washed with water and brine, dried (Na2SO4), filtered and evaporated in vacuo. The residue was purified by FCC, using 0-5% MeOH in DCM to give the title compound as a dark green gum (0.30 g, 63%). LCMS (Method 3): Rt 2.46 min, m/z 364 [MH+].
