合成路线1
该中间体在本合成路线中的序号：(II)Reduction of 2-methylindole-3-glyoxylamide (I) with LiAlH4 affords 2-methyltryptamine (II). 4-Formylcinnamic acid (III) is esterified with methanolic HCl, and the resulting aldehyde ester (IV) is reductively aminated with 2-methyltryptamine (II) in the presence of NaBH3CN to give (V). The title hydroxamic acid is then obtained by treatment of ester (V) with aqueous hydroxylamine under basic conditions (1). Scheme 1.
