Certain N-cyanoimidates are prepared by (a) contacting a propendimidate dihydrohalide salt with two equivalents of a base to produce a bisimidate; (b) contacting the bisimidate with cyanogen chloride to produce a mixture of N-cyanoimidate and a monohydrohalide bisimidate salt; (c) isolating the N-cyanoimidate. The N-cyanoimidate may, by heating, be converted to a pyrimidine, useful as a herbicide intermediate.
