The title compound was prepared by following general procedure 4. To a solution of 3,9-dimethyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (200 mg, 0.93 mmol) in 50% aq. NaOH solution (3 mL) was added, tetra n-butyl ammonium chloride (12 mg, 0.046 mmol) followed by 5-vinylpicolinic acid (153 mg, 1.0 mmol). The reaction mixture was heated at 90° C. for overnight, and the reaction was monitored by TLC. After completion of reaction, the reaction mixture was diluted with water, extracted with ethyl acetate. The organic layer was separated, dried over Na2SO4, and concentrated under reduced pressure. The crude product was purified by reverse phase chromatography to afford 7 mg of 5-(2-(3,9-dimethyl-2,3,4,5-tetrahydroazepino[4,5-b]indol-6(1H)-yl)ethyl)picolinic acid as the TFA salt.
