실험 절차

2-fluoro-4-nitrophenol (36.73 g, 0.234 mol) was added to a dried chlorobenzene (5v/w, 250 mL). The mixture was heated to 145° C. Intermediate VII (12.5 g, 0.039 mol) was added to the reaction solution. The reaction was conducted at this temperature for 20 h. After completion of the reaction, the solvent was evaporated off to produce a grey solid. This solid was dissolved in CH2Cl2, and washed with a satureated saturated K2CO3 solution several times. The organic layer was collected. The solvent was dried off to produce a solid, which is recrystallized with ethanol to produce a yellow solid (49.16 g) in a yield of 71.4%.
