실험 절차

The 2-(2,4,5-trifluorophenyl)-4, 4-dimethyl-2-oxazoline was also treated with lithium diisopropylamide followed by methyl iodide to give 2-(2,4,5-trifluoro-3-methylphenyl)-4,4-dimethyl-2-oxazoline. This intermediate was, in turn, treated with lithium diisopropylamide, then with methyl iodide, to give 2-(2,4,5-trifluoro-3,6-dimethylphenyl)-4,4-dimethyl-2-oxazoline. Hydrolysis of the oxazoline gave 2,4,5-trifluoro-3,6-dimethylbenzoic acid, which was elaborated into 1-cyclopropyl-6,7-difluoro-1,4-dihydro-5,8-dimethyl-4-oxo-3-quinolinecarboxylic acid in the usual manner.
