To a solution of {1-[4-cyano-2-methyl-3-(trifluoromethyl)phenyl]-1H-tetrazol-5-yl}methyl acetate (Intermediate 47, 330 mg, 1.02 mmol) in water (2 mL) and tetrahydrofuran (4 mL), cooled in an ice bath, was added lithium hydroxide monohydrate (42.6 mg, 1.02 mmol). The reaction was stirred at room temperature for 1 hour and 30 min. The organic solvent was removed from the reaction under vacuum and the residual mixture diluted with water (30 mL) and extracted with DCM (2*50 ml). The organic extracts were combined, dried (hydrophobic frit) and the solvent removed to yield the titled compound as a white solid.
