ABSTRACT:
An improved process for the synthesis of 2-(2'-thienyl)ethylamine from suitably functionalized derivatives of 2-(2'-thienyl)ethanol employing ammonia gas in the presence of a metal salt or liquid ammonia and alkyl ketone as a solvent. The 2-(2'-thienyl)ethylamine produced by this process is advantageously converted to ticlopidine.
