PROCEDURE
实验过程
To a solution of N-{3-bromo-4-[4-(diethylcarbamoyl-phenyl-methyl)-piperazin-1-yl]-phenyl}-2-ethyl-butyramide (66 mg, 0.12 mmol) in DMF (1.5 mL) was added CuI (1.3 mg, 0.01 mmol), triphenylphosphine (73 mg, 0.28 mmol), diethylamine (220 μL, 2.1 mmol), trimethylsilylacetylene (22 μL, 0.15 mmol) and dichlorobis(triphenylphosphine)palladium (II) (5.0 mg, 0.01 mmol). This solution was heated in a focused microwave reactor at 120° C. for 5 min, after which the solution was concentrated and purified by reverse phase HPLC to provide N-{4-[4-(diethylcarbamoyl-phenyl-methyl)-piperazin-1-yl]-3-trimethylsilanylethynyl-phenyl}-2-ethylbutyramide (10.5 mg, 16%). This compound (18 mg, 0.03 mmol) was dissolved in MeOH and treated with K2CO3 (9.0 mg, 0.06 mmol). After 1 h, the solids were filtered off, the filtrate concentrated, and the product purified by reverse phase HPLC to afford the title compound (10 mg, 63%). MS: 489.4.
