実験手順
The method described in Part D of Example 109 was used with the following modification. The reaction was carried out in refluxing toluene, and 8-ethoxymethyl-5,6-dimethyl-7-[2-(3-pyrimidin-5-ylprop-2-ynyloxy)ethyl]-7H-imidazo[4,5-c]tetrazolo[1,5-a]pyridine (6.20 g, 15.3 mmol) was used in lieu of 8-ethoxy-5,6-dimethyl-7-[2-(pyridin-4-ylmethoxy)ethyl]-7H-imidazo[4,5-c]tetrazolo[1,5-a]pyridine. The crude product was purified by column chromatography on silica gel (200 g, eluting with 95:5 dichloromethane:methanol) to provide 0.852 g of 2-(ethoxymethyl)-6,7-dimethyl-1-{2-[(3-pyrimidin-5-ylprop-2-ynyl)oxy]ethyl}-1H-imidazo[4,5-c]pyridin-4-amine as a white powder, mp 122–124° C.
