It has been shown that the highest yields (15%) of 7-bromo-5-(o-chlorophenyl)-3-hydroxy-1,2-dihydro-3H-1,4-benzodiazepin-2-one are obtained by the use of the cells of actinomycetes immobilized in poly(vinyl alcohol) in the presence of the cosubstrate 7-bromo-5-(o-chlorophenyl)-3-methyl-1,2-dihydro-3H-1,4-benzodiazepin-2-one.
