Versuchsvorschrift

A solution of 2-(2-tritylaminothiazol-4-yl)-(Z)-2-(2-carbamoyl-2-propyloxyimino)acetic acid (2.00 g, 3.9 mmol), 1-hydroxybenzotriazole (0.560 g, 4.29 mmol) and N,N'-dicyclohexylcarbodiimide (0.840 g, 4.10 mmol) in dimethylacetamide (24 ml) was stirred at room temperature for 4 hours. To this solution was added a solution of 7β-amino-3-[(1-amino-1H-tetrazol-5-yl)thiomethyl]-3-cephem-4-carboxylic acid (1.41 g, 4.29 mmol) and triethylamine (0.790 g, 8.58 mmol) in dimethylacetamide (10 ml) and water (1.4 ml) and the mixture was allowed to react at room temperature for 17 hours. Then the mixture was treated in a manner similar to that described in Example 6, (c) to give pale yellow powder of 7β-[2-(2-tritylaminothiazol-4-yl)-(Z)-2-(2-carbamoyl-2-propyloxyimino)acetamido]-3-[(1-amino-1H-tetrazol-5-yl)thiomethyl]-3-cephem-4-carboxylic acid (2.27 g, 70.5%).
