In a manner similar to that described in Example 1 (Step 1), 6-chloro-1-trityl-1H-pyrazolo[4,3-c]pyridin-3(2H)-one (3B) was treated with 1-bromo-2-methoxyethane and potassium carbonate (DMF, room temperature, overnight) to provide 6-chloro-3-(2-methoxyethoxy)-1-trityl-1H-pyrazolo[4,3-c]pyridine (84% yield).
