実験手順

A suspension of 0.5 g 7-chloro-6-fluoro-1-(5-fluoro-pyridin-2-yl)-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid ethyl ester (1.37 mmol) in a mixture of 1.5 ml acetic acid and 1.5 ml 25% HCl was stirred at 90° C. over night. The reaction was monitored by HPLC. The suspension was poured into 50 ml water, the colorless crystals filtered and dried.
