Procedure:
Meanwhile, 121 mg of pivaloyloxymethyl 7-amino-3-methoxymethyl-3-cephem-4-carboxylate and 141 mg of N,N-diethylaniline were dissolved in 5 ml of methylene chloride and stirred at -5° C.

The reaction mixture was stirred for 15 minutes and then concentrated by evaporation under reduced pressure. To the residue were added 20 ml of ethyl acetate and 5 ml of water, and the ethyl acetate layer was separated, washed, in turn, with 5 ml of a saturated aqueous solution of sodium bicarbonate, 5 ml of a 5% w/v aqueous solution of hydrogen chloride and 5 ml of a saturated aqueous solution of sodium chloride, and finally dried over anhydrous magnesium sulphate. The drying agent was filtered off and the filtrate was concentrated by evaporation under reduced pressure. The resulting residue was subjected to column chromatography through 10 g of silica gel eluted with a 2:1 by volume mixture of ethyl acetate and hexane, to afford 55 mg of pivaloyloxymethyl 7-[2-(2-chloroacetamidothiazol-4-yl)-2-methoxyiminoacetamido]-3-methoxymethyl-3-cephem-4-carboxylate.

Procedure:
A suspension of 2 g of 8-chloro-7-fluoro-1-methyl-4-oxo-1,4-dihydro-benzo[b][1,8]naphthyridine-3-carboxylic acid in 7.44 g of 2,2-dimethylpiperazine and 20 cm3 of pyridine is heated at a temperature close to 115° C. for 44 hours. The reaction mixture is concentrated to dryness under reduced pressure (20 kPa) at about 60° C. The residue is taken up in 50 cm3 of ethanol and again concentrated, under reduced pressure, under the above conditions. The solid obtained is taken up in 50 cm3 of diethyl ether, drained, washed with twice 30 cm3 of the same solvent and taken up in 120 cm3 of water and 2 g of methanesulphonic acid. A very small amount of insoluble matter is removed by filtering through diatomaceous silica. 2 cm3 of 50% aqueous potassium hydroxide solution are added to the solution obtained. The precipitate formed is drained and washed with 3 times 25 cm3 of water and a single amount of 50 cm3 of ethanol at about 50° C. 1.6 g of 8-(3,3-dimethyl-1-piperazinyl)-7-fluoro-1-methyl-4-oxo-1,4-dihydro-benzo[b][1,8]naphthyridine-3-carboxylic acid are obtained in the form of a yellow solid melting at 362°-365° C., solvated by 4.9% of water.
