Abstract

1343410 L-α-hydrazino-#-phenylpropionic acid compounds MERCK & CO Inc 17 Dec 1970 [25 March 1970] 35694/73 Divided out of 1343407 Heading C2C L-Compounds containing not more than 10% of the D-form and having the Formula I (in which each of R<SP>1</SP> and R<SP>2</SP> is H, OH, C 1-6 alkoxy, phenoxy or benzyloxy, each of R<SP>3</SP> and B<SP>4</SP> is H or C i - e alkyl and R<SP>6</SP> is H, C 1-6 alkyl, a metal atom or, in the case of a multivalent metal, an equivalent of the metal) are prepared by reacting an L-compound containing not more than 10% of the D-form and having the Formula II (in which X‹ is halogen, arylsulphonyl or alkylsulphonyl) with hydrazine, an acyl hydrazine or an alkali metal salt of hydrazine, followed, when an acyl hydrazine is used, by hydrolysis. Compounds I are useful as decarboxylase inhibitors and antihistaminics.
