Procedure

To a suspension of 60% sodium hydride (294 mg, 7.4 mmol) in N,N-dimethylformamide (2.5 mL) was added methanesulfonamide (713 mg, 7.5 mmol) at room temperature. The resulting mixture was stirred at 25° C. for 1 h. A solution of 6-chloro-3,3-dimethyl-2-(3-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-8-carboxylic acid (300 mg, 0.75 mmol) and 1,1′-carbonyldiimidazole (244 mg, 1.5 mmol) in N,N-dimethylformamide (2.0 mL) was stirred at 70° C. After stirring at 70° C. for 1 h, the above suspension of methanesulfonamide and sodium hydride in N,N-dimethylformamide was added and the mixture was allowed to stir at 25° C. for 1 h. Purification 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-3,3-dimethyl-2-(3-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-8-carbonyl]-methanesulfonamide (107 mg, 30%) as a white solid: LC/MS m/e calcd for C25H30ClN3O4S (M+H)+: 505.05, observed: 504.0.
