Reaction Steps

To a solution of 1,1-dimethylethyl (1S,4S)-5-({1-[4-(trifluoromethyl)phenyl]-1H-tetrazol-5-yl}methyl)-2,5-diazabicyclo[2.2.1]heptane-2-carboxylate (470 mg, 1.107 mmol, Intermediate 17) in methanol was added 4M hydrogen chloride in 1,4-dioxane (5 mL, 20 mmol). The reaction mixture was stirred at room temperature for 2 hours. The reaction mixture was concentrated in vacuo and poured onto a 5 g SCX cartridge. The cartridge was washed with methanol (2 column volumes) and eluted with ammonia in methanol (2 column volumes). The ammonia in methanol fractions were concentrated and the residue dried in vacuo to yield the title compound as white crystals (363 mg)
