标题 :Preparation of 2-(2'-thienyl) alkylamines and derivatives thereof and synthesis of 4,5,6,7- thieno [3,2-c] pyridine derivatives therefrom
发明人：KHATRI HIRALAL N; DEHOFF BRADLEY S
权利人:SANOFI SA
摘要:An improved process for the synthesis of 2-(2 min -thienyl)ethylamine from suitably functionalized derivatives of 2-(2 min -thienyl)ethanol employing ammonia gas in the presence of a metal salt or liquid ammonia and alkyl ketone as a solvent. The 2-(2 min -thienyl)ethylamine produced by this process is advantageously converted to the carbamic acid salt, which is suitably reconverted to 2-(2 min -thienyl)ethylamine, a useful intermediate in the synthesis of ticlopidine.
