Versuchsvorschrift

The third embodiment of the present invention is directed to a method of making a starting material useful in the synthesis of (E)-3-(4-{[2-(2-methyl-1H-indol-3-yl)-ethylamino]-methyl]-phenyl)-acrylic acid methyl ester hydrochloride salt. In particular, the third embodiment of the present invention is directed to a method of making 2-methyltryptamine comprising the steps of: (a) providing an admixture of phenylhydrazine and 5-chloro-2-pentanone in ethanol at a first temperature; (b) adding ethanol to the admixture and refluxing the mixture; (c) distilling ethanol; (d) adding water to the residual solution; (e) cooling the residual solution to form 2-methyltryptamine.
