Procedure

A mixture of 2-(3-fluoro-5-pyrrolidin-1-yl-phenyl)-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (50 mg, 0.14 mmol), 1-3-dimethylaminopropyl-3-ethylcarbodiimide hydrochloride (39 mg, 0.20 mmol), 4-dimethylaminopyridine (24.4 mg, 0.20 mmol), methane sulfonamide (40 mg, 0.42 mmol) in dichloromethane (3 mL) was heated for 12 hours at 60° C. 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-pyrrolidin-1-yl-phenyl)-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carbonyl]-methanesulfonamide (22 mg, 35%) as a light yellow solid: LC/MS m/e calcd for C23H28FN3O3S (M+H)+: 446.6, observed: 446.2.
