Participants

Reaction Steps

To a stirred and refluxed Grignard complex, previously prepared starting from 8.15 parts of 1-bromo-3-fluorobenzene, 1.2 parts of magnesium and a small amount of 1,1'-oxybisethane was added a solution of 5 parts of 1-methyl-1H-benzotriazole-7-carboxaldehyde in 80 parts of 1,1'-oxybisethane. After stirring for 2 hours at room temperature, the reaction mixture was poured into 300 parts of water. The product was extracted three times with 65 parts of dichloromethane. The combined extracts were dried, filtered and evaporated. The residue was stirred for 15 minutes in 100 parts of water and 13 parts of petroleum ether at room temperature. The product was filtered off and dried, yielding 7.6 parts (95.2%) of α-(3-fluorophenyl)-1-methyl-1H-benzotriazole-7-methanol; mp. 152° C. (int. 19).
