Abstract

NEW MATERIAL:The 3-amino-2-methylpyridine derivative of formulaI(R is H, lower alkyl or acyl) or its salt.
EXAMPLE: 3-Amino-4-aminomethyl-5-hydroxymethyl-2-methylpyridine dihydrochloride.
USE: Pharmaceuticals. Esp. an intermediate for the preparation of vitamin B6.
PROCESS: The compound of formulaIcan be prepared either by treating the 3- amino-4-cyano-2-methylpyridine derivative of formula II (novel substance) or its salt with a proper reducing agent, or by reducing the compound of formula II in the presence of a catalyst such as Raney-Ni, etc. The novel compound of formula II can be obtained by the reaction of N-formylamino-propinonitrile with γ-substituted crotononitrile.
