A procedure for the preparation of benzylpyrimidine derivatives of the general formula in which R1 and R2 each independently represent a C1-3alkyl, C1-3alkoxy, C2-3alkenyl, or C2-3alkenyloxy group. Z represents the group -N (R4) 2, -N3, -N = N-N (R4) 2, or -NH-NH2, R4 represents a C1-3 alkyl or C2-3'alkenyl group A represents an oxygen atom bonded to one of the cyclic nitrogen atoms and n has a value of zero or 1, and its salts, the process of which comprises diazolating a compound of the formula **(See formula)** where R1, R2, A and n have the aforementioned meaning, and then react the product with sodium azide, with an amine of the formula NH (R4) 2 or with an alkaline sulfite, and convert, if desired, a compound of formula I obtained in a salt.
