Procedure

3′-aminomethyl-5-(1H-tetrazol-5-yl)-biphenyl-2-ol (0.31 g, 1.16 mmol) was dissolved in dimethylformamide (10 mL) and the solution was treated with triethylamine (0.8 mL, 5.8 mmol) and tert-butylisocyanate (0.14 mL, 1.27 mmol). The mixture was stirred at room temperature for 2 hours. Workup with ethyl acetate and water, followed by drying afforded 0.56 g (quant.) of the crude 1-tert-butyl-3-[2′-hydroxy-5′-(1H-tetrazol-5-yl)-biphenyl-3-ylmethyl]-urea.
