Procedure
A solution of [1-{(3-cyano-benzyl)-[1-(4-phenyl-1H-imidazol-2-yl)-ethyl]-carbamoyl}-2-(4-hydroxy-2,6-dimethyl-phenyl)-ethyl]-carbamic acid tert-butyl ester (0.070 g, 0.12 mmol) in 3 mL of EtOH was treated with 1.0 mL of 30% hydrogen peroxide followed immediately by 0.1 mL of a 6M aqueous solution of NaOH. The reaction mixture was stirred vigorously for 18 h and quenched by pouring into chilled (5-10° C.) water. The aqueous solution was extracted five times with Et2O and the combined extracts were dried over MgSO4, filtered, and concentrated to provide 0.051 g of [1-{(3-carbamoyl-benzyl)-[1-(4-phenyl-1H-imidazol-2-yl)-ethyl]-carbamoyl}-2-(4-hydroxy-2,6-dimethyl-phenyl)-ethyl]-carbamic acid tert-butyl ester as a colorless residue (HPLC: 84% @ 254 nm and 77% @ 214 nm). MS (ES+) (relative intensity): 612.5 (100) (M+1). This sample was of sufficient quality to use in the next reaction without further purification.
