Reaction Conditions

Reaction Steps

To a suspension of methanesulfonamide (480 mg, 5.0 mmol) in N,N-dimethylformamide (5 mL) was added sodium hydride (200 mg, 5.0 mmol). The resulting mixture was stirred at 25° C. for 1 h to afford Solution A36. A solution of 2-(3-methoxy-phenyl)-4,4-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (310 mg, 1.0 mmol) and 1,1′-carbonyldiimidazole (320 mg, 2.0 mmol) in N,N-dimethylformamide (5 mL) was stirred at 70° C. for 1 h and cooled to room temperature to afford Solution B36. Solution B36 was added to Solution A36 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-[2-(3-methoxy-phenyl)-4,4-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carbonyl]-methanesulfonamide (116 mg, 30%) as a white solid: MS (ESI) M+1=389.3.
