Reaction Steps
In the manner described in Example 11, 4.815 g of 3-acetoxymethyl-7β-[(2R)-2-(4-BOC-aminophenyl)-2-(4-ethyl-2,3-dioxopiperazine-1-carboxamido)-acetamido]-3-cephem-4-carboxylic acid diphenylmethyl ester are reacted with 2.2 g of p-toluenesulphonic acid monohydrate in 40 ml of acetonitrile and worked up. 3-Acetoxymethyl-7β-[(2R)-2-(4-aminophenyl)-2-(4-ethyl-2,3-dioxopiperazine-1-carboxamido)-acetamido]-3-cephem-4-carboxylic acid diphenylmethyl ester p-toluenesulphonate is obtained. [α]D20 =+15°±1° (0.94% in CH3OH).
