実験手順
A mixture of ethyl 2-(8-chloro-1,2,3,4-tetrahydro-2-methylpyrido[4,3-b]indol-5-yl)acetate (100 mg) and pyrrolidine (1 ml) was heated at 120° C. for 15 h to obtain 59 mg of 2-(8-chloro-1,2,3,4-tetrahydro-2-methylpyrido[4,3-b]indol-5-yl)-1-(pyrrolidin-1-yl)ethanone after purification on neutral alumina chromatography eluting with methanol-dichloromethane gradient. The free base was converted into its oxalate salt by treatment of oxalic acid (1 equiv) in anhydrous THF.
