Reaction Steps

A mixture of 2-[3-fluoro-5-(2-oxo-pyrrolidin-1-yl)-phenyl]-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (130 mg, 0.34 mmol), 1-3-dimethylaminopropyl-3-ethylcarbodiimide hydrochloride (98 mg, 0.51 mmol), 4-dimethylaminopyridine (62 mg, 0.51 mmol), methane sulfonamide (97 mg, 1.02 mmol) in dichloromethane (10 mL) was heated for at 65° C. for 12 hours. Removal of the solvent afforded an oil residue. 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% formic acid in water) afforded N-{2-[3-fluoro-5-(2-oxo-pyrrolidin-1-yl)-phenyl]-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carbonyl}-methanesulfonamide (45 mg, 29%) as a light yellow solid: LC/MS m/e calcd for C23H26FN3O4S (M+H)+: 460.5, observed: 460.2.
