실험 절차

A mixture of 0.614 g of 1-(4-bromo-benzene-sulfonyl)-4-(2,4-dimethylphenyl)-piperazine, 0.42 g of bis-(pinacolato)-diboron, 0.025 g of 1,1′-bis-(diphenylphosphino)-ferrocene, 0.033 g of [1,1′-bis(diphenyl-phosphino)ferrocene]palladium-dichloride (complex with CH2Cl2), 0.442 g of potassium acetate in 8 ml of degassed dioxane are heated to 90° C. in a sealed tube under N2 for 7 hours. To the resulting mixture 10 ml of degassed dioxane, 0.371 g of 2-[2-(4-methoxypyridin-2-yl)ethyl]-6-iodo-3H-imidazo[4,5-b]pyridine (starting material A1), 0.113 g of tetrakis(triphenylphosphine)-palladium(0) and a solution of 0.27 g of potassium carbonate and 0.083 g of lithium chloride in 10 ml of degassed water are added under N2. The tube is sealed again, the mixture is heated to 115° under N2 for 23 hours and, after cooling, addition of water and adjusting the pH to 7, it is extracted three times with ethylacetate. The combined organic phases are dried over sodium sulfate, concentrated and the residue is chromatographed on a silica gel column (dichloromethane/methanol 25-20:1). Concentration of the chromatographically pure fractions and crystallization of the residue from ethylacetate gives 0.27 g of the title compound as a solid of m.p. 208-209° C. The mass spectrum shows the molecular peak MH+ at 583.5 Da.
