Procedure

To a round bottom flask, a mixture of methyl 2-(4-(chlorosulfonyl)phenyl)-3,3-dimethyl-3,4-dihydroquinoline-6-carboxylate (396 mg, 1.0 mmol) in dichloromethane (10 mL) was added dropwise to a mixture of methylamine hydrochloride (68 mg, 1.0 mmol) and N,N-diisopropyl ethylamine (0.54 mL, 3.0 mmol) in dichloromethane (10 mL). The resultant mixture was allowed to stir at room temperature for 10 hours. The reaction mixture was washed by water several times, dried over anhydrous magnesium sulfate. Filtered and concentrated to provide methyl 3,3-dimethyl-2-(4-(N-methylsulfamoyl)phenyl)-3,4-dihydroquinoline-6-carboxylate as a yellow oil (190 mg). MS (ES+APCI) M+1=389.1.
