The mechanism of the reactions of 2-alkoxymethylene-3-alkoxypropionitrile and 2-dialkoxymethyl-3-alkoxypropionitrile with acetamidine was studied. The results show that these two nitriles react with acetamidine in completely different manners. In the case of the reaction of 2-alkoxymethylene-3-alkoxypropionitrile with acetamidine, the final product (2-methyl-4-amino-5-alkoxymethylpyrimidine) can be
