Procedure

1-tert-Butyl-3-[2′-hydroxy-5′-(1H-tetrazol-5-yl)-biphenyl-3-ylmethyl]-urea (0.56 g, 1.5 mmol) was dissolved in a mixture of chloroform (0.2 mL, 3 mmol) and sodium hydroxide (10% aqueous, 5 mL, 12 mmol) and the mixture was refluxed for 5 days. The mixture was worked up with 1N hydrochloric acid and ethyl acetate. Some solids precipitated out of solution and were filtered and dried. The organic layer from the extraction was dried and combined with the solids above gives 1-tert-butyl-3-[3′-formyl-2′-hydroxy-5′-(1H-tetrazol-5-yl)-biphenyl-3-ylmethyl]-urea as a 3:1 mixture of starting material to product.
