反応手順
Dry hydrogen chloride was passed for 3 hours into a solution of 9-cyanofluorene (15 67.85; g.; see, for example, J. Amer. Chem. Soc., 1949, 71, 1500) in ether (1 l.) ans absolute ethanol (45 ml.) at 0°C. The mixture was left at 0°C overnight, the solid filtered, washed with ether and dried under vacuum at room temperature to give the title compound as its hydrochloride hemihydrate (17.61 g., m.p. 262°-263°C dec.). Found: C, 68.5; H, 6.05; N, 4.95%. C16H13NO.HCl.1/2H2O requires C, 687.85; H, 6.05; N, 4.95%.
