1-(2-bromoethyl)pyrrolidine;hydrobromide

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Preparation of the title compound was carried out according to General Method 8. 4-Methylphenylhydrazine hydrochloride (2 g, 12.6 mmol), 1-(2-bromoethyl)pyrrolidine hydrobromide (8.1 g, 31.5 mmol), triethyl amine (17.5 ml, 126 mmol) and N-methyl-4-piperidone hydrochloride (1.87 g, 12.6 mmol) were combined in ethanol (15 ml) to obtain 180 mg of 2,3,4,5-tetrahydro-2,8-dimethyl-5-(2-(pyrrolidin-1-yl)ethyl)-1H-pyrido[4,3-b]indole after on purification on silica gel (230-400 mesh) chromatography eluting with acetone-hexane gradient. The free base was converted into its dioxalate salt by treatment of oxalic acid (2 equiv.) in anhydrous THF.
