1-Substituted 4,4,6-trimethyl-1,4-dihydropyrimidine-2(3H)-thiones (2) on heating in 11M-HCl at 100-110 deg C are converted into the corresponding 2-substituted-amino-4,6,6-trimethyl-6H-1,3-thiazines (4) and/or thioureas.But at 95-100 deg C, Dimroth rearrangement products, e.g. the corresponding 2-substituted-amino-4,4,6-trimethyl-4H-1,3-thiazenes (3) are formed.
