Popis: Dehydration of the nitrone-hydroxylamine (II) with toluene- p -sulphonyl chloride and triethylamine gives the rearranged product. 2,3,4,5-tetrahydro 5,5-dimethyl 3-oxo-2-(4′,5′,5′-trimethylpyrrolidin-2′ ylidene) pyridine (III). The benzoate of (III) undergoes rearrangement in dilute acid to give the pyrrolo-imidazole (XI).
