実験手順

Bromomethyl 3-methylbutanoate (1.328 g, 6.7 mmole) was added to a solution of (6R,7R)-3-carbamoyloxymethyl-7-[(Z)-2-(fur-2-yl)-2-methoxyiminoacetamido]ceph-3-em-4-carboxylic acid, potassium salt (2.772 g, 6 mmole) in purified N,N dimethylformamide (18 ml). The mixture was allowed to react for 15 minutes and was then worked up as described in Example 4 to give the slightly impure title compound (2.809 g).
