実験手順
A TBAF solution (1M in THF, 4.6 ml, 4.6 mmol) is added to a solution of 3,6,9-tris-(triphenylsilyl)carbazole (8.7 g, 9.2 mmol) in CH2Cl2 (150 ml). After stirring for one hour, thin layer chromatography shows complete deprotection. The solvent is removed under reduced pressure, and the residue is heated under reflux in cyclohexane (150 ml). After cooling, the suspension is filtered. The residue is filtered through SiO2 (10:1 cyclohexane:EtOAc) to obtain the desired product (7.6 g, 97%). 1H NMR (CDCl3, 400 MHz): δ=7.4 (m, 20H), 7.6 (m, 14H), 8.18 (s, 2H), 8.20 (s, 1H).
