Procedimiento

0.047 ml of benzene sulfonyl chloride are added to 0.115 g of 2-[2-(4-methoxypyridin-2-yl)ethyl]-6-(4-aminophenyl)-3H-imidazo[4,5-b]pyridine (example 27) in 1 ml of pyridine and the mixture is stirred at ambient temperature for three hours. The solvent is evaporated in vacuo and the residue is is chromatographed on a silica gel column (dichloromethane/methanol 30–20:1+1% triethylamine). Concentration of the chromatographically pure fractions and drying gives 0.093 g of the title compound as a solid of m.p. 251–253° C. The mass spectrum shows the molecular peak MH+ at 486.3 Da.
