To a mixture of 6.5 parts of 1-(tert.-butyl)-3-azetidinol and 7.9 parts of α-naphthol 0.2 part of potassium hydroxide was added, and the mixture was heated at 160° C. for 24 hours. The reaction mixture was cooled and then dissolved in 100 parts of ether. The solution was washed twice with 50 parts of 2N-sodium hydroxide aqueous solution and extracted three times with 50 parts of 2N-hydrochloric acid aqueous solution. The extract was washed with 50 parts of ether and made alkaline by addition of 2N-sodium hydroxide aqueous solution. Extraction was conducted three times with 50 parts of benzene, and the extract was dried over anhydrous sodium sulfate. Then benzene was distilled off and the residue was solidified by drying under reduced pressure. The solid residue was subjected to distillation under reduced pressure. As a result 5 parts of 1-(α-naphthoxy)-3-(tert.-butylamino)-2-propanol boiling at 175°-180° C. under 1.5 mm Hg were obtained. A part of the product was dissolved in 5 parts of anhydrous ether and the product was converted to a hydrochloride by adding a hydrochloric acid gas to the resulting ether solution. The hydrochloric was recrystallized twice from a mixed solvent of ethyl acetate and ether. As a result 1-(α-naphthoxy)-3-(tert.-butylamino)-2-propanol hydrochloride having a melting point of 182°-184° C was obtained.

Procedure:
To a suspension of 7-[2-ethoxyimino-2-(5-amino-1,2,4-thiadiazol-3-yl)acetamido]-3-[3-(N-methylformamido)-1-pyridiniomethyl]-3-cephem-4-carboxylate (syn isomer) (2.75 g) in methanol (27.5 ml) was added concentrated hydrochloric acid (1.39 ml) and the mixture was stirred for 75 minutes. The solvent was evaporated and the residue was triturated in acetone. The obtained powder was suspended in water (70 ml), adjusted to pH 4 to 5 with aqueous solution of sodium bicarbonate and subjected to column chromatography on a non ionic adsorption resin "Diaion HP 20" (Trademark: Prepared by Mitsubishi Chemical Industries) (100 ml). After the column was washed with water, the elution was carried out with 15% aqueous isopropyl alcohol. The eluates containing an object compound were collected, evaporated to remove isopropyl alcohol under reduced pressure and lyophilized to give 7-[2-ethoxyimino-2-(5-amino-1,2,4-thiadiazol-3-yl)acetamido]-3-(3-methylamino-1-pyridiniomethyl)-3-cephem-4-carboxylate (syn isomer) (1.41 g), mp 149° to 157° C.
