Reaction Steps

To a solution of methyl 2-(4-aminophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxy late (50 mg, 0.16 mmol), cyclohexanecarboxylic acid (0.03 mL, 0.24 mmol) and N,N-diisopropylethylamine (0.05 mL, 0.32 mmol,) in dichloromethane (5 mL) was added phosphorus oxychloride (0.02 mL, 0.24 mmol) via syringe below 0° C. The mixture was stirred at room temperature for 16 h under nitrogen. The solvent was removed and the residue was washed with dichloromethane/petroleum ether, the precipitate was collected to afford methyl 2-(4-(cyclohexane carboxamido)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate as a yellow solid, 42 mg, yield: 53%.
