A mixture of 2-[3-chloro-4-[chloro(4-chlorophenyl)methyl]phenyl]-1,2,4-triazine-3,5(2H,4H)-dione (0.0075 mol) and 1,8-diazabicyclo[5.4.0]undec-7-ene (0.025 mol) in 2-methylpropanol (25 ml) was stirred for 72 hours at 80° C. The solvent was evaporated. The residue was purified by column chromatography over silica gel (eluent: CH2Cl2/CH3OH 97.5/2.5). The pure fractions were collected and the solvent was evaporated. The residue was dried, yielding 0.8 g (25%) of (±)-2-[3-chloro-4-[(4-chloro-phenyl)(2-methylpropoxy)methyl]phenyl]-1,2,4-triazine-3,5(2H,4H)-dione (compound 133).
