Procedure

A mixture of 3,3-dimethyl-2-(3-methoxy-5-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (120 mg, 0.3 mmol), 1-3-dimethylaminopropyl-3-ethylcarbodiimide hydrochloride (87 mg, 0.45 mmol), 4-dimethylaminopyridine (55 mg, 0.45 mmol), cyclopropane sulfonamide (109 mg, 0.9 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 cyclopropanesulfonic acid [3,3-dimethyl-2-(3-methoxy-5-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-6-carbonyl]-amide (52 mg, 35%) as a light yellow solid: LC/MS m/e calcd for C26H33N3O5S (M+H)+: 500.6, observed: 500.2.
