Reaction Steps

To a stirred mixture of 40.4 parts of 1-(4-fluorophenylmethyl)-N-(4-piperidinyl)-1H-benzimidazol-2-amine hydrobromide and 400 parts of methanol are added 8.8 parts of oxirane and stirring is continued overnight at room temperature. The reaction mixture is evaporated and the residue is taken up in water. The precipitated product is filtered off and dried, yielding 29 parts (64%) of 4-[1-(4-fluorophenylmethyl)-1H-benzimidazol-2-ylamino]-1-piperidineethanol monohydrobromide; mp. 248.2° C.
