合成路线1
该中间体在本合成路线中的序号：(XXII)The intermediate hydrazine (XXIII) was obtained by two alternative methods. Alkylation of 4-(3-pyridyl)imidazole (II) with the chiral mesylate (XIX), prepared from (R)-1,3-butanediol (XVIII), furnished, after desilylation with tetrabutylammonium fluoride, the imidazolyl butanol (XX). Condensation of alcohol (XX) with di-tert-butyl azodicarboxylate in the presence of PPh3 yielded the hydrazine dicarboxylate (XXII), which was then deprotected to hydrazine (XXIII) under acidic conditions.
