Reaction Steps

The substitution reaction at the 9-position was performed according to the general procedure for the synthesis of 9-substituted fluorenes described above in item IV(i). 1-Methylfluorene (47) (3.01 g, 16.7 mmol) was used instead of fluorene, n-BuLi (8.06 ml, 20 mmol, 2.5 M in hexane), RX=1-iodoethane (3.39 g, 21.7 mmol). 48 was isolated to give a colorless oil (3.33 g, 95%).
