3-MethylthiopropylaminおよびTyramin誘導体

抄録

3-Methylthiopropylamine, obtained by decarboxylation of DL-methionine with tetralin, showed the same boiling point as that of the sample obtained by Schneider and agreed in the boiling point of the base and melting point of the hydrochloride of the sample obtained by following the method of Akabori, Kaneko, and others. The product was obtained in 90% yield. 3-Nitrotyramine, obtained by decarboxylation of 3-nitro-L-tyrosine, and its hydrochloride showed the same melting point as that of the sample obtained by nitration of tyramine by Waser. 4-Methoxyphenethylamine, obtained from L-tyrosine methyl ether by the same method, was identical with the sample synthesized by the Rosenmund method and was identified by mixed fusion with the reduction product of β-nitro-4-methylstyrol with lithium aluminum hydride.
