2-Aminothiophenes and 2-amino-4,5-dihydrothiophenes were selectively and conveniently synthesized from 4-thiazolidinone derivatives. The meaningful product 10m was efficiently synthesized, which is a commonly-used intermediate for preparing olanzapine. The present method holds many advantages, such as easy operation, high yields, is catalyst-free and uses water as the solvent.

The present invention relates to the compound 2-ethyl-10-(4-methyl-1-piperazinyl)-4H-thieno[2,3-b][1,5]benzodiazepine and its use as is or in substantially pure form in the treatment of CNS disorders including schizophrenia and bipolar disorder. The compound is prepared by reacting a substituted thiophene compound with 2-fluoronitrobenzene to form, after ring closure and reaction with N-methylpiperazine, the title compound. The compound is then purified to substantially pure form and is useful as an antipsychotic. The compound may also be combined with other active ingredients including HMG CoA reductase inhibitors such as lovastatin or simvastatin and/or antidepressants such as fluxoetine or other SSRIs to form medically useful combination products useful in treating psychotic conditions and depression while also preventing any rise beyond the normal range of cholesterol levels in any subset of patients that might develop such a condition.
