실험 절차

17.1 g (60 millimoles) of 1-(3'-chloropropyl)-1,2,3,4-tetrahydro-β-carboline hydrochloride were dissolved in 240 ml of dimethylformamide while heating, and the solution was then cooled to 5° C. in an ice bath. 11.5 g (150 millimoles) of acetyl chloride and immediately thereafter 23.7 g (300 millimoles) of pyridine were added dropwise to the thoroughly stirred solution, the temperature not rising above 5° C. during this operation. Thereafter, stirring was continued for a further 2 hours at this temperature, after which the reaction mixture was poured onto ice water. The precipitate was filtered off under suction and washed thoroughly with water. 16.9 g (97%) of crystals of melting point 166°-168° C. (ethanol) were isolated.
