Versuchsvorschrift

7-Amino-3-hydroxymethyl-3-cephem-4-carboxylic acid (9.21 g) was suspended in water (200 ml) and neutralized to pH 7.5 with dicyclohexylamine (7 g). To the resultant solution was added dropwise salicylaldehyde. (5.42 g). After stirring at ambient temperature for 2 hours, the precipitates were collected by filtration and dried to give 7-salicylideneamino-3-hydroxymethyl-3-cephem-4-carboxylic acid dicyclohexylamine salt (17.4 g).
