Procedure
In analogy to Example 1 b), from 1,3-dicyanobenzene and sodium methylate in methanol followed by ammonium chloride there is obtained 3-cyano-benzamidine hydrochloride and therefrom with diethyl (2-methoxy-phenoxy)malonate there is obtained rac.-3-[5-(2-methoxy-phenoxy)-4,6-dioxo-1,4,5,6-tetrahydro-pyrimidin-2-yl]-benzonitrile as a white product. From this compound with PCl5 and POCl3 there is obtained 3-[4,6-dichloro-5-(2-methoxy-phenoxy)-pyrimidin-2-yl]-benzonitrile with a melting point of 155-156° from EtOAc. Reaction with 4-tert.-butylbenzenesulphonamide K yields 4-tert.-butyl-N-[6-chloro-2-(3-cyanophenyl)-5-(2-methoxyphenoxy)-pyrimidin-4-yl]-benzenesulphonamide.
