Reaction Conditions

Reaction Steps

To a suspension of methanesulfonamide (160 mg, 1.65 mmol) in N,N-dimethylformamide (3 mL) was added sodium hydride (66 mg, 1.65 mmol). The resulting mixture was stirred at 25° C. for 1 h to afford Solution A32. A solution of 2-(3-carbamoyl-phenyl)-4,4-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (100 mg, 0.33 mmol) and 1,1′-carbonyldiimidazole (110 mg, 0.66 mmol) in N,N-dimethylformamide (3 mL) was stirred at 70° C. for 1 h and cooled to room temperature to afford Solution B32. Solution B32 was added to Solution A32 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 3-(6-methanesulfonylaminocarbonyl-4,4-dimethyl-1,2,3,4-tetrahydro-quinolin-2-yl)-benzamide (13 mg, 10%) as a white solid: MS (ESI) M+1=402.3.
