A CONVENIENT METHOD FOR THE SYNTHESIS OF 1-R-1,2,3,4-TETRAHYDROBENZOTHIENO[2,3- c ]PYRIDINE DERIVATIVES

New 1-R-2-methyl-1,2,3,4-tetrahydrobenzothieno[2,3- c ]pyridine derivatives have been obtained by cyclization of 2-(1-benzothiophen-3-yl)ethylamines with aromatic and heteroaromatic aldehydes in the presence of triisopropylchlorosilane.
