실험 절차

To a solution of 2-(2-(2-chloro-N-cyclopropyl-6-methylphenylsulfonamido)-ethoxy)acetic acid AC8 (0.225 mmol) in dichloromethane (10 ml/mmol) was added diisopropyl ethylamine (4 equiv.) at 0° C. followed by the addition of HOBT (1.0 equiv.) and EDCI (1.5 equiv.). The resulting solution was stirred at 25° C. for 15 min. It was again cooled to 0° C. and a solution of N-((4-(4-cyclopropyl-piperazin-1-yl)piperidin-4-yl)methyl)isonicotinamide dihydrochloride AM12 (1.2 equiv.) in DMF (2 ml) was added. The reaction mixture was stirred for 16 h at 25° C. The mixture was diluted with dichloromethane, washed with saturated ammonium chloride solution, brine, saturated sodium bicarbonate and finally again with brine. The organic layer was dried over sodium sulfate and evaporated to dryness under reduced pressure to give the crude product which was purified by column chromatography. Yield: 55%. MS, Rt=2.8 min, m/z=673.4 [MH]+.
