실험 절차

A mixture of 2-n-butylamino-4-fluoronitrobenzene (10 mmol), 4-t-butylphenol (13 mmol), solid K2CO3 (30 mmol) and DMF (30 mL) was heated with stirring at 90° C. for 10 h. The reaction was quenched by cold H2O (50 mL), and the resulting mixture was extracted with EtOAc (3×100 mL). The combined EtOAc extracts were washed with brine (2×50 mL) and dried (anhydrous Na2SO4). The solvent was removed in vacuo, and the crude products were purified by silica gel column chromatography (eluting with 10% EtOAc in hexane), giving 2-n-butylamino-4-(4-t-butylphenoxy)nitrobenzene.
