PROCEDURE

实验过程

(E)-3-[1-(4-Bromo-benzenesulfonyl)-1H-pyrrol-3-yl]-N-(tetrahydro-pyran-2-yloxy)-acrylamide (0.95 g) and [5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridin-2-yl]-carbamic acid tert-butyl ester (1.00 g) are dissolved under an inert gas atmosphere in dimethylethylenglycole (35 mL), and Pd(PPh3)3Cl2 (0.22 g) and a sodium carbonate solution (2.21 g dissolved in 21 water) is added and it is heated for 0.5 h at 90° C. After cooling the mixture is diluted with water, extracted with chloroform, and the combined organic phases are dried and evaporated. The residue is purified by silica gel flash chromatography CHCl3/THF (4:1). 0.97 g of the title compound are obtained with a melting point of 140-146° C.
