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.

权利人:SYNTEX INC
摘要:The carbamate salt of 2-(2'-thienyl)-alkylamines and particularly the ethylamine and its method of synthesis are disclosed. The carbamate salt of 2-(2'-thienyl)ethylamine is a stable, easily transportable crystalline material that can be converted to 2-(2'-thienyl)ethylamine, a useful intermediate in the synthesis of 5[(2-chlorophenyl)methyl]-4,5,6,7-tetrahydrothieno-[3,2-c]pyridine hydrochloride, also known as ticlopidine hydrochloride. The synthesis is carried out by reacting an amine of formula (I): (I) with CO2 in a hydrocarbon solvent to obtain the carbamate salt of formula II: II

摘要:Disclosed is a process for the preparation of N-alkyl carbazole. Said process comprises: a) chlorinating cyclohexanone to form 2-chlorocyclohexanone; b) reacting 2-chlorocyclohexanone with N-ethyl aniline to form 2-(N-ethyl anilino)cyclohexanone; c) cyclizing 2-(N-ethyl anilino) cyclohexanone by refluxing with simultaneous water removal to obtain 9-ethyltetrahydrocarbazole; d) treating 9-ethyl-tetrahydrocarbazole with concentrated hydrochloric acid followed by water wash for removing N-ethyl aniline; e) dehydrogenating 9-ethyltetrahydrocarbazole by heating 9-ethyltetrahydrocarbazole in a solvent, in presence of a catalyst to obtain N-alkyl carbazole.

标题:Chemical synthesis of conducting polypyrrole
发明人：WALKER JOHN A; WITUCKI EDWARD F; WARREN LESLIE F
权利人:ROCKWELL INTERNATIONAL CORP
摘要:Production of electrically conductive polypyrrole of enhanced stability by treating a liquid pyrrole with a solution of a strong oxidant, capable of oxidizing pyrrole to a pyrrole polymer, and oxidizing the pyrrole by such strong oxidant in the presence of a relatively large organic dopant anion, and precipitating a conductive polypyrrole. The strong oxidant, e.g., Fe3+ ion, and dopant anion, which can be an alkyl or aryl sulfonate, e.g., methylbenzenesulfonate, or a perfluorinated carboxylate, e.g., trifluoroacetate, anion, can be derived from a single compound, e.g., the anion serving as dopant for the polypyrrole.
