실험 절차

To a solution of 16.4 g. of the product of Example 1 in 500 ml. of dichloromethane, 7.3 g. of cyclopropanecarbonyl chloride is added, followed by dropwise addition of 10 ml. of triethylamine. A mildly exothermic reaction takes place, after which stirring of the mixture is continued at room temperature overnight. The mixture is then washed with 1N hydrochloric acid and water, and dried over anhydrous sodium carbonate. On evaporation to dryness, crude cyclopropyl 1,2,3,4,8,9-hexahydropyrido[4',3':2,3]indolo[1,7-ab][1]benzazepin-3-yl ketone is obtained as a glassy product, m.p. 149°-152° on recrystallization from ethanol. A solution of 8.6 g. of this material in 120 ml. of tetrahydrofuran is added dropwise to a suspension of 2.3 g. of lithium aluminum hydride in 180 ml. of tetrahydrofuran. On completion of the addition, the mixture is first refluxed for 4 hours, then allowed to stir at room temperature overnight and finally decomposed in the usual manner. After filtering off the inorganic salts, the filtrate is dried over anhydrous sodium carbonate, evaporated in vacuo; the residue is dissolved in a 1:1 mixture of ethyl acetate-benzene and chromatographed on a 14 × 2.2 cm. column of basic alumina, activity I. The eluate is taken down to dryness; the residual oil dissolved in absolute alcohol, saturated with ethanolic hydrogen chloride, and once again evaporated to dryness. Upon crystallization of the residue from acetone, 3-(cyclopropylmethyl)-1,2,3,4,8,9-hexahydropyrido[4',3':2,3]indolo[1,7-ab][1]benzazepine hydrochloride, m.p. 267°, is obtained.
