Reaction Steps

Prepared analogously to Example 1g from C-(6-bromo-3H-imidazo[4,5-b]pyridin-2-yl)methylamine, TBTU, diisopropylethylamine, and 3-methyl-4-(2,5-dihydropyrrol-1-ylcarbonyl)benzoic acid in tetrahydrofuran. Purification is effected by chromatography on silica gel (gradient: dichloromethane/ethanol=100:0□80:20). Yield: 240 mg (96%); Rf value: 0.68 (silica gel; dichloromethane/ethanol=8:2+2% ammonia solution); C20H18BrN5O2 (440.30); mass spectrum: (M+H)+=440/442 (bromine isotope).
