Procedure

To a solution of methyl 2-(4-fluoro-3-nitrophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (105 mg, 0.32 mmol) in dichloromethane (5 mL) was added N,N-diisopropylethylamine (83 mg, 0.64 mmol) followed by benzoyl chloride (49 mg, 0.35 mmol) at 0° C. under nitrogen. The reaction mixture was then stirred at room temperature for 16 hours. The solvent was removed and the residue was purified by preparative Thin layer chromatography (silica gel, petroleum ether/ethyl acetate=3:1) to afford methyl 2-(3-benzamido-4-fluorophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate 130 mg (94%) as a pale yellow solid. MS (ESI+APCI) M+1=433.
