2-(8-chloro-2-methyl-3,4-dihydro-1H-pyrido[4,3-b]indol-5(2H)-yl)acetic acid (0.2 g, 0.719 mmol) in 10 mL of DCM was taken, EDCI.HCl (137 mg, 0.719 mmol) was added and stirred for 10 min at RT, N-Boc piperazine (133 mg, 0.719 mmol) was added to the reaction mixture and stirred for 24 h at RT. Reaction was monitored by TLC & LCMS. After completion of the reaction, reaction mixture was concentrated and purified by column chromatography (neutral alumina; 2% Methanol-DCM) then purified by reverse phase chromatography to afford 90 mg of tert-butyl 4-(2-(8-chloro-2-methyl-3,4-dihydro-1H-pyrido[4,3-b]indol-5(2H)-yl)acetyl)piperazine-1-carboxylate.
