Versuchsvorschrift

4-Morpholinecarbonyl chloride (202 μL, 1.73 mmol) was added to a solution of 1-(4-aminobutyl)-2-ethoxymethyl-6-methyl-1H-imidazo[4,5-c]pyridin-4-amine (0.435, 1.57 mmol) in a mixture of triethylamine (280 μL, 2.04 mmol) and chloroform (8 mL). The reaction mixture was stirred at ambient temperature for 4 hours then it was diluted with chloroform (20 mL) and washed with saturated sodium bicarbonate (10 mL). The organic layer was dried over magnesium sulfate and then concentrated under reduced pressure. The residue was purified by column chromatography (30 g of silica gel eluting with 1 L of 2% methanol in chloroform containing 0.5% triethylamine. The resulting glassy solid was triturated with acetonitrile to provide 0.417 g of N-{4-[4-amino-2-(ethoxymethyl)-6-methyl-1H-imidazo[4,5-c]pyridin-1-yl]butyl}morpholine-4-carboxamide as an off white powder, m.p. 156.5-159.5° C.
