实验过程
To a solution of methyl[3-formyl-5-(trifluoromethyl)benzyl]{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}carbamate (37.0 mg, 0.065 mmol) (Example 40) in THF (123 μL) was added t-butanol (360 μL), 2-methyl 2-butene (123 μL), and a solution of NaClO2 (12.9 mg, 0.014 mmol) and NaH2PO4 (19.7 mg, 0.014 mmol) in H2O (152 μL). The reaction was stirred vigorously for two hours at room temperature, diluted with EtOAc (30 mL), and poured into 1N HCl (10 mL). The aqueous layer was extracted with EtOAc (3×20 mL) and the combined organic extracts were washed with brine (10 mL), dried over Na2SO4, filtered, and concentrated. Purification by flash chromatography with 0.1% acetic acid in 8% MeOH/CH2Cl2 afforded 3-{[{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}(methoxycarbonyl)amino]methyl}-5-(trifluoromethyl)benzoic acid. Rf=0.35 (10% MeOH/CH2Cl2).
