실험 절차

To a suspension of 60% sodium hydride (361 mg, 9 mmol) in N,N-dimethylformamide (5 mL) was added methanesulfonamide (865 mg, 9.1 mmol) at room temperature. The resulting mixture was stirred at 25° C. for 1 h to afford Solution A62. A solution of 6-chloro-4,4-dimethyl-2-(3-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-8-carboxylic acid (520 mg, 1.3 mmol) and 1,1′-carbonyldiimidazole (422 mg, 2.6 mmol) in N,N-dimethylformamide (3 mL) was stirred at 70° C. for 1 h and cooled to room temperature to afford Solution B62. Solution B62 was added to Solution A62 and the resulting mixture was stirred at 25° C. for 1 h. To the reaction mixture was added water (0.5 mL). The mixture was filtered to remove the insoluble solid, and the filtrate was purified by Waters automated flash system (column: Xterra 30 mm×100 mm, sample manager 2767, pump 2525, detector: ZQ mass and UV 2487, solvent system: acetonitrile and 0.1% ammonium hydroxide in water) afforded N-[6-chloro-4,4-dimethyl-2-(3-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-8-carbonyl]-methanesulfonamide (50 mg, 8%) as a white solid: MS (ESI) M+1=478.2.
