Abstract:
5-Isothiocyanato-6-methylpyrimidine-2,4(1H,3H)-dione was formed in the course of the reaction between N-hydroxy-6-methyluracil-5-carboximidoyl chloride and a series of thioureas in MeOH in the presence of Et3N. The transformation follows the Hoffman rearrangement mechanism, with the nitrile N-oxide being the key intermediate.
