Procedure

A mixture of 3,3-dimethyl-2-(3-methyl-5-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (150 mg, 0.39 mmol), 1-3-dimethylaminopropyl-3-ethylcarbodiimide hydrochloride (110 mg, 0.59 mmol), 4-dimethylaminopyridine (72 mg, 0.59 mmol), methane sulfonamide (110 mg, 1.17 mmol) in dichloromethane (5 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-[3,3-dimethyl-2-(3-methyl-5-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-6-carbonyl]-methanesulfonamide (71 mg, 40%) as a light yellow solid: LC/MS m/e calcd for C24H31N3O4S (M+H)+: 458.6, observed: 458.2.
