N-methylpyrrole is produced by passing N-methylpyrrolidine vapour and hydrogen at elevated temperatures over a platinum or palladium catalyst supported on silica gel. The amount of platinum or palladium is conveniently from 1 to 10% of the weight of the gel and the process is carried out at ...
During the preparation and storage of cefepime, degradation of the beta-lactam ring can occur to yield N-methylpyrrolidine (NMP). The primary concerns with degradation are loss of potency and the potential toxicity of degradation products to patients. The US Pharmacopeia (USP) specifies a limit ...
