1-(4-Cyclohex-1-enylphenyl)-3-(3,5-dichlorophenyl)-1-{4-[1-hydroxy-2-(2H-tetrazol-5-yl)ethyl]benzyl}urea (30 mg, 0.05 mmol) was dissolved in DCM (1.5 ml) and acetic acid anhydride (15 μl) was added. The mixture was stirred at room temperature overnight, and then taken to dryness. The residual oil was dissolved in ethanol (2 ml), and heated to reflux for 0.5 min. Then cooled and evaporated to dryness. The residue was stripped twice from acetonitrile to give a quantitative yield of the title compound.
