Procedure

2.1 Grams (8.3 mmols) of a 1-bromophenanthrene was dissolved in 43 ml of heptane, and to which was added 5.3 ml (1.6 mols/l, 8.5 mmols) of butyllithium to obtain a 1-lithiophenanthrene, which was, then, cooled down to −5° C. 1.6 Grams (5.2 mmols) of the 3.9-dimethoxy-5-hydroxybenzo[c]fluorene-7-one was added thereto, and the mixture was stirred for one hour. Then, THF was added thereto at a temperature of not higher than 0° C., and the mixture was stirred at this temperature for 2 hours. The conversion was 40%. The mixture was continuously stirred for another 20 hours, but the conversion remained to be 40%.
