실험 절차

EX-655A) The 3-(phenoxy)aniline (555 mg, 3 mmol) and 3-hydroxybenzaldehyde (366 mg, 3 mmol) were dissolved in 7 mL of 1,2-dichloroethane. Acetic acid (0.189 mL, 3.15 mmol) and solid NaBH(OAc)3 (1.01 g, 5 mmol) were added. The mixture was stirred at room temperature for 3 h, then acidified with 1 N HCl solution. After neutralizing to pH 7.5 with 2.5 N sodium hydroxide, the mixture was extracted with methylene chloride. The organic layer was washed with brine and water, then dried over anhydrous MgSO4, and evaporated to give 609 mg (69%) of the desired N-(3-phenoxyphenyl)[[3-hydroxyphenyl]methyl]amine product as a brown oil, which was greater than 90% pure by reverse phase HPLC analysis. MS m/z=291.
