실험 절차

To an ice-cold mixture of methyl 2-(4-fluoro-3-nitrophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (170 mg, 0.52 mmol) and N,N-diisopropylethylamine (140 mg, 1.03 mmol) in 5 mL of dichloromethane was dropwise added a solution of 2-chloro-4-fluorobenzoyl chloride (120 mg, 0.62 mmol) in 3 mL dichloromethane under nitrogen. Then the resulted mixture was stirred at R.T. for overnight. Thin layer chromatography and LC-MS indicated that the starting material was consumed completely. The solvent was removed by rotary evaporation. The residue was purified by silica gel (petroleum ether/ethyl acetate=3:1) to afford 189 mg of methyl 2-(3-(2-chloro-4-fluorobenzamido)-4-fluorophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate as a yellow solid; yield: 76%. MS (ESI+APCI) M+1=485.
