1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 44159566, compound

Participants

Reaction Steps

3-(1,2,3,4-tetrahydro-2,8-dimethylpyrido[4,3-b]indol-5-yl)propanoic acid was mixed with EDCI and cyclohexylmethanamine in dichloromethane and the reaction mixture was stirred for 16 h to obtain N-(cyclohexylmethyl)-3-(1,2,3,4-tetrahydro-2,8-dimethylpyrido[4,3-b]indol-5-yl)propanamide 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.
