合成路线1
该中间体在本合成路线中的序号:(II)The oxidation of eserine (I) by means of H2O2 and KHCO3 produced the geneseroline carbamate (II), which was hydrolyzed to geneseroline (III) employing 62% sulfuric acid at 85 C. The desired carbamate was then obtained by condensation of (III) with 2-ethylphenyl isocyanate (IV) either in the presence of K2CO3 in acetone or in the presence of t-BuOK under sonication, and the title compound was then isolated as the corresponding hydrochloride salt.
