Reaction Conditions

Reaction Steps

To a suspension of methanesulfonamide (665 mg, 7 mmol) in N,N-dimethylformamide (3 mL) was added sodium hydride (280 mg, 7 mmol). The resulting mixture was stirred at 25° C. for 1 h to afford Solution A64. A solution of 6-chloro-4,4-dimethyl-2-[3-(2-oxo-oxazolidin-3-yl)-phenyl]-1,2,3,4-tetrahydro-quinoline-8-carboxylic acid (400 mg, 1 mmol) and 1,1′-carbonyldiimidazole (325 mg, 2 mmol) in N,N-dimethylformamide (2 mL) was stirred at 70° C. for 1 h and cooled to room temperature to afford Solution B64. Solution B64 was added to Solution A64 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-(2-oxo-oxazolidin-3-yl)-phenyl]-1,2,3,4-tetrahydro-quinoline-8-carbonyl}-methanesulfonamide (37 mg, 7%) as a white solid: MS (ESI) M+1=478.0.
