Reaction Conditions

Reaction Steps

To a suspension of 60% sodium hydride (91 mg, 2.2 mmol) in N,N-dimethylformamide (1.5 mL) was added cyclopropanesulfonamide (278 mg, 2.3 mmol) at room temperature. The resulting mixture was stirred at 25° C. for 1 h. A solution of 2-(4′-methanesulfonyl-biphenyl-3-yl)-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (100 mg, 0.23 mmol) and 1,1′-carbonyldiimidazole (75 mg, 0.46 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 cyclopropanesulfonamide 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 cyclopropanesulfonic acid [2-(4′-methanesulfonyl-biphenyl-3-yl)-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carbonyl]-amide (25 mg, 20%) as a white solid: LC/MS m/e calcd for C28H30N2O5S2 (M+H)+: 539.69, observed: 539.1.
