Abstract
Methyl 4-chloromethyl-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate has been prepared and rearranged to give methoxy- and cyano- derivatives of methyl 2-oxo-2,3,4,5-tetrahydro-1H-1,3-diazepine-6-carboxylate, which undergo acid-catalysed ring contraction to give methyl 1-carbamoyl-2-methylpyrrole-3-carboxylate.
