Participants

Reaction Steps

The general method described in Part A of Example 81 was followed, using 2-(8-ethoxymethyl-5,6-dimethyl-7H-imidazo[4,5-c]tetrazolo[1,5-a]pyridin-7-yl)ethanol (4.51 g, 15.5 mmol) in lieu of tert-butyl 2-hydroxyethylcarbamate and 3-bromo-1-phenylpropyne, prepared as described in Part A of Example 7, in lieu of propargyl bromide. The crude product was triturated with diethyl ether, isolated by filtration, and dried under reduced pressure to provide 5.93 g of 8-ethoxymethyl-5,6-dimethyl-7-{2-[(3-phenylprop-2-ynyl)oxy]ethyl}-7H-imidazo[4,5-c]tetrazolo[1,5-a]pyridine as a yellow solid.
