実験手順

A solution of 3b (54.0 mg, 0.099 mmol), pyrazole (50.7 mg, 0.745 mmol), salicylaldoxime (19.8 mg, 0.145 mmol), copper(I) oxide (16.6 mg, 0.116 mmol) and cesium carbonate (265 mg, 0.812 mmol) in acetonitrile (1.00 mL) was heated to 120° C. in a sealed microwave vial for a total of 60 min. The reaction mixture was cooled to rt, concentrated in vacuo, and the resulting crude residue was purified by preparative reversed phase HPLC on YMC Pack Pro C18 stationary phase (CH3CN/H2O as eluent, 0.05% TFA as modifier), followed by lyophilization of the purified fractions to afford the title compound 10a. m/z (ES) 531 (MH)+.
