PROCEDURE

实验过程

A mixture of 4-bromo-5-nitrothiophene-3-carbonitrile (0.5 g, 2.1 mmol), 2-(tributylstannyl)thiazole (1.2 g, 3.2 mmol), dioxane (3.5 mL), and tetrakis(triphenylphosphine)palladium(0) (0.23 g, 0.21 mmol) was heated by microwave to 130° C. for 30 min under nitrogen. The reaction mix was concentrated under reduced pressure, and the resulting dark oil was purified by column chromatography using a mobile phase of 20% EtOAc/hexanes to give 5-nitro-4-(thiazol-2-yl)thiophene-3-carbonitrile (180 mg) as an oil. LCMS of this material revealed an m/z of 238.0 with a retention time of 1.807 min method [1].
