Procedure

A mixture of 3,3-dimethyl-2-(4-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (70 mg, 0.19 mmol), 1-3-dimethylaminopropyl-3-ethylcarbodiimide hydrochloride (55 mg, 0.29 mmol), 4-dimethylaminopyridine (35 mg, 0.29 mmol), methane sulfonamide (54 mg, 0.57 mmol) in dichloromethane (10 mL) was heated for at 65° C. for 12 hours. Removal of the solvent to 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-(4-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-6-carbonyl]-methanesulfonamide (34 mg, 40%) as a light yellow solid: LC/MS m/e calcd for C23H29N3O4S (M+H)+: 444.6, observed: 444.2.
