Procedure
In the presence of triethylamine (0.50 mL, 3.4 mmol), 8-(ethoxymethyl)-5,6-dimethyl-7-prop-2-ynyl-7H-imidazo[4,5-c]tetraazolo[1,5-a]pyridine (0.442 g, 1.55 mmol) was reacted with N-hydroxypyridine-3-carboximidoyl chloride generated from 3-pyridinecarboxyaldehyde oxime (prepared as described in Part A of Example 5, 0.38 g, 3.11 mmol) and N-chlorosuccinimide (0.42 g, 3.11 mmol) in THF (5 mL) using the method described in Part B of Example 5. After purification by flash chromatography (silica gel, elution with 95:5 dichloromethane/methanol) and trituration in diethyl ether, the product 8-(ethoxymethyl)-5,6-dimethyl-7-[(3-pyridin-3-ylisoxazol-5-yl)methyl]-7H-imidazo[4,5-c]tetraazolo[1,5-a]pyridine was obtained (0.171 g) as a white powder.
