As shown, in a two-step process, 4,6-dimethylpyrimidine is reacted with dimethylamine hydrochloride and formaldehyde to provide the corresponding 4,6-bis(dimethylaminoethyl)pyrimidine. This dimethylaminoethyl compound is methylated and deaminated in the presence of a base to provide the desired 4,6-divinylpyrimidine.
