Reaction Steps
A Parr vessel was charged with acetic acid 2-[(5,6-dimethyl-8-nitrotetrazolo[1,5-a]pyridin-7-yl)amino]ethyl ester (50.0 g, 170 mmol), 5% platinum on carbon (5.00 g), toluene (600 mL), and 2-propanol (50 mL) and purged with nitrogen. The vessel was then placed under hydrogen pressure (20 psi, ) for 20 hours at room temperature. The reaction mixture was filtered through a layer of CELITE filter aid, and the filter cake was washed with 90:10 dichloromethane:methanol. The filtrate was concentrated under reduced pressure to provide a dark gray solid, which was triturated with diethyl ether, isolated by filtration, and dried to provide 41.0 g of acetic acid 2-[(8-amino-5,6-dimethyltetrazolo[1,5-a]pyridin-7-yl)amino]ethyl ester as a light gray solid.
