Reaction Steps

To a suspension of methanesulfonamide (85 mg, 0.89 mmol) in N,N-dimethylformamide (2 mL) was added sodium hydride (36 mg, 0.89 mmol). The resulting mixture was stirred at 25° C. for 1 h. A solution of 3,3-dimethyl-2-[3-(1-methyl-1-methylcarbamoyl-ethylamino)-phenyl]-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (50 mg, 0.127 mmol) and 1,1′-carbonyldiimidazole (41 mg, 0.253 mmol) in N,N-dimethylformamide (1.5 mL) was stirred at 70° C. for 1 h. Then 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 2-[3-(6-methanesulfonylaminocarbonyl-3,3-dimethyl-1,2,3,4-tetrahydro-quinolin-2-yl)-phenylamino]-2,N-dimethyl-propionamide (15 mg, 25%) as a white solid: LC/MS m/e calcd for C24H32N4O4S (M+H)+: 473.61, observed: 473.1.
