Definition

ChEBI: Vorozole is a member of benzotriazoles.

Manufacturing Process

To a stirred solution of 28.4 parts of 1H-1,2,4-triazole in 135 parts of N,N- dimethylformamide were added 11.4 parts of a sodium hydride dispersion 80% under nitrogen atmosphere. After stirring for 1 hour at room temperature, a solution of 40 parts of 6-[chloro(4-chlorophenyl)-methyl]-1- methyl-1H-benzotriazole in 90 parts of N,N-dimethylformamide was added to the mixture. The whole was stirred for 1 hour at 60°C. The reaction mixture was diluted with 50 parts of water and the whole was evaporated. The residue was extracted with ethyl acetate. The extract was washed with water, dried, filtered and evaporated. The residue was purified by column chromatography over silica gel using a mixture of dichloromethane and methanol (99:1 by volume) as eluent. The pure fractions were collected and the eluent was evaporated. The residue was crystallized from a mixture of 2-propanone and 1,1'-oxy-bis-ethane (ether). The product was filtered off and dried, yielding 13 parts (29.2%) of 6-[(4-chlorophenyl)-(1H-1,2,4-triazol-1-yl)methyl]-1-methyl- 1H-benzotriazole; MP: 178.9°C. A resolution of enantiomers any usual method gave crystals from 2-propanol, MP: 130-135°C. [α] D 20 = 8.0° (plus or minus) (c = 10 in CH 3 OH).
