Procedure

To a mixture of 1-(4-{1-Ethyl-1-[4-(1H-tetrazol-5-yl)-phenyl]-propyl}-2-methyl-phenoxy)-3,3-dimethyl-butan-2-one (0.37 g, 0.88 mmol) and EtOH (5 mL) was added NaBH4 (0.037 g, 0.97 mmol) and the solution stirred for 1 hour. The solids were removed by filtration and the solution concentrated. The residue was purified by ISCO (10-30 [89% EtOAc: 10% MeOH: 1% AcOH] gradient) to furnish the title compound (0.32 g, 0.76 mmol, 86%).
