Reaction Steps
5.65 g (25 mmol) of 6-(trifluoromethyl)-1,4-naphthoquinone, 9.82 g (about 37 mmol) of 1,2-dibromobenzocyclobutene (contaminated with a little 2-bromo-1-iodobenzocyclobutene) and 100 ml of xylene are kept under reflux for 16 hours using a water separator. The mixture is cooled, and the precipitate is filtered off and washed with xylene. The yield is 5.82 g (71%); m.p. 253°-254°.
