PROCEDURE

实验过程

Free base of the titled compound was prepared from 4-ethoxy-2-nitroaniline according to the preparation of (E)-1-(2-pyridyl)-2-styryl-5-trifluoromethyl-1H-benzimidazole (Example 57). The free base and oxalic acid were dissolved into ethyl acetate. Concentration and recrystallization from ethyl acetate/n-hexane yielded the titled compound.
