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