Reaction of 4-amino-5-chloro-2-methoxybenzoic acid (I) with 1,2-dibromoethane in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene afforded bromoethyl ester (II). This was then condensed with a mixture of cis and trans 3,5-dimethylpiperidines (III), and the resulting mixture of amines was finally separated by column chromatogaphy to provide the target cis compound.
