Reaction Steps

4 parts of 1-hydroxy-2-(2-chlorophenyl)-phenanthroimidazole in 30 parts of tetrahydrofuran are initially taken, and 2 parts of pyridine and 3.6 parts of acetic anhydride are then added. Tne mixture is stirred for five hours at room temperature, after which 40 parts of ethyl acetate are added to the resulting solution. The organic phase thus obtained is washed several times with water and dried over sodium sulfate, after which the solvent is stripped off. The solid which remains is recrystallized from methyl ethyl ketone/cyclohexane.
