Reaction Steps
A mixture of freshly prepared 2,6-difluorobenzoyl isocyanate (1.85 g) and 3,4-dichlorophenyl isocyanate (1.89 g) is heated at 120° C. for a period of 16 hours, and then cooled. Recrystallisation of the solid which was obtained from ethyl acetate yielded 3-(3,4-dichlorophenyl)-6-(2,6-difluorophenyl)-3,4-dihydro-2H-1,3,5-oxadiazin-2,4-dione, white crystals, m.p. 196°-197° C.
