Hydrobromicacid reacts with 2-methallylthio- and 2-prenylthio-4(3Н)-pyrimidinones with participation of the double bond to give the products of heterocyclization, and with 2-allylthio- and 2-propargylthio-6-methyl-4(3Н)-pyrimidinones, with the retention of the double bond and the formation of hydrobromides.

Hydrochloricacid reacts with 5-ethyl-2-methallylsulfanyl-6-methylpyrimidin-4(3H)-ones to protonate the nitrogen atom; it adds to the double bond of 2-prenylsulfanyl-6-(trifluoromethyl)pyrimidin-4(3H)-one and gives the addition and heterocyclization products in the case of 2-prenylsulfanyl-6-methylpyrimidin-4(3H)-one.
