Abstract In this work the results of the reaction of β‐alkoxyvinyl trihalomethyl ketones 1, 2a‐e , with guanidine hydrochloride are reported. Depending on the ketone 1 or 2 and the conditions under which the reactions were carried out, 4‐trihalomethyl‐2‐amino pyrimidines, β‐alkoxyvinyl carboxylic acids, or β‐acetal carboxylic esters were obtained.
