Procedure

8.40 g (40.7 mmol) 2,6-di-tert-butylphenol was dissolved in 100 ml dried DMSO. 2.32 g (58 mmol) sodium-hydroxide and 8.5 g (54 mmol) p-chloronitrobenzene were added into the DMSO solution. The DMSO solution was heated to 100˜120° C. for 12 hrs with stirring. Then the reaction mixture was allowed to cool to room temperature and poured into distilled water. The aqueous solution was acidified to pH 2˜4 and yellow precipitate was collected by filtration. The yellow precipitate was washed with water and dried. The crude yield was 85%. The yellow precipitate was purified by recrystallizing in cyanomethane, mp 157˜160° C.
