Procedure
To a solution of [1-(4-cyanophenyl)-1H-tetrazol-5-yl]methyl acetate (2.48 g, 10.2 mmol, Intermediate 8) in water (15 mL), methanol (15 mL) and tetrahydrofuran (THF) (30 mL), cooled in an ice bath, was added lithium hydroxide (0.244 g, 10.2 mmol). The reaction mixture was stirred at 0-5° C. for 1.5 hours. The reaction mixture was acidified with the addition of 2N HCl (5.5 ml). The majority of the organic solvent was then removed from the reaction mixture under vacuum leading to precipitation of a white solid which was filtered then dried under vacuum at 40° C. for 18 hours to yield the title compound as a white solid (1.43 g)
