Procedure
2-(8-chloro-1,2,3,4-tetrahydro-2-methylpyrido[4,3-b]indol-5-yl)acetic acid was mixed with EDCI and 1-butanol and the reaction mixture was stirred for 16 h to obtain butyl 2-(8-chloro-1,2,3,4-tetrahydro-2-methylpyrido[4,3-b]indol-5-yl)acetate 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.
