Isobutyryl chloride → Methyl-2-(4-fluoro-3-isobutyramidophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate

Participants

Reaction Steps

To a solution of methyl 2-(4-fluoro-3-nitrophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (150 mg, 0.46 mmol) and N,N-diisopropylethylamine (0.15 mL, 0.91 mmol) in dichloromethane (10 mL) was added isobutyryl chloride (0.053 mL, 0.50 mmol) via syringe with ice cooling. The resultant mixture was stirred for an additional 20 h. The solvent was removed in vacuo and the residue was purified by column chromatography (petroleum ether:ethyl acetate=3:1) to afford 183 mg of methyl-2-(4-fluoro-3-isobutyramidophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate. Yield: 97%.
