Procedure

To a solution of methyl 2-(3-amino-4-chlorophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (200 mg, 0.58 mmol) in 8 mL of dichloromethane, was added N,N-diisopropylethylamine (150 mg, 1.16 mmol) under nitrogen atmosphere. Then a solution of cyclohexanecarbonyl chloride (127 mg, 0.87 mmol) was added via syringe with an ice bath. The mixture was stirred for 1.5 h. The mixture was purified by column chromatography to afford 250 mg of methyl 2-(4-chloro-3-(cyclohexanecarboxamido)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate as a crude product. (Yield: 95%).
