Abstract: Preparation of an unsymmetrical 4,6-bis(aryloxy)pyrimidine derivatives of formula (I) is new. The process comprises reacting a 4-halo-6-(aryloxy)pyrimidine compound of formula (II) with >=1 molar equivalent of a 1-4C trialkylamine, a 5-14 membered unsaturated heterocyclic amine optionally substituted to 1-3 1-4C alkyl, or 1-4C alkoxy groups in the presence of an aromatic hydrocarbon and/or a halogenated aromatic hydrocarbon solvents, to form an ammonium halide of formula (III), and reacting the ammonium halide with >=1 phenyl compound of formula (IV) and a base. R1, R8 = H or halo; R1, R7 = H halo, CN, NO2 alkyl, haloalkyl, alkoxy, alkylthio, amino, alkylamino, dialkylamino, alkoxyalkyl, haloalkoxyalkyl or alkoxycarbonyl; R2, R6 = H, halo, alkyl, haloalkyl, haloalkoxy, haloalkoxyalkyl, alkoxycarbonyl, haloalkoxycarbonyl, haloalkylsulphinyl, haloalkylsulphonyl, nitro, or cyano; R3, R5 = H, halo, alkyl or alkoxy; and R4 = H, cyano, alkyl, haloalkyl, alkoxy, alkylthio, alkylsulphinyl, or phenyl; provided that >= 1 of R2 and R6 is not H, and that the aryloxy groups are different. Q = R10N(R9)(R11) or substituted heteroaryl groups of formulae (a)-(g). R9, R10, R11 = 1-4C alkyl, or R910 = 5-6 membered ring with 3-5 O, S or NR-14 atoms; R11 = 1-4C alkyl; Z = O, S or NR14; R12, R13 = H, 1-4C alkyl, 1-4C alkoxy; or R12, R13 = 5-6 membered saturated or unsaturated ring optionally interrupted with O, S, or NR14, and optionally substituted with 1-3 1-4C alkyl or 1-4C alkoxy groups; and R14 = 1-4C alkyl.
