Procedure
To a stirred mixture of 1.12 parts of 3-furancarboxylic acid, 2.02 parts of N,N-diethylethanamine and 195 parts of dichloromethane are added 2.6 parts of 2-chloro-1-methylpyridinium iodide at room temperature. After stirring for 1 hour, 3.3 parts of N-[1-(2-aminoethyl)hexahydro-1H-azepin-4-yl]-3-[(5-methyl-2-furanyl)methyl]-3H-imidazo[4,5-b]pyridin-2-amine are added and stirred overnight at room temperature. The mixture is poured into water and the layers are separated. The organic layer is dried, filtered and evaporated. The residue is purified by column chromatography over silica gel using a mixture of trichloromethane and methanol (96:4 by volume) as eluent. The pure fractions are collected and the eluent is evaporated, yielding 2.19 parts (36.1%) of N-[2-[hexahydro-4-[[3-[(5-methyl-2-furanyl)methyl]-3H-imidazo[4,5-b]pyridin-2-yl]amino]-1H-azepin-4-yl]ethyl]-3-furancarboxamide as a residue (compound 190).
