| titleOfInvention | PREPARING TETRAHYDRO-THIENO [3,2-c] AND [2,3-c] PYRIDINE¹DERIVATIVES |
| abstract | PROCESS FOR THE PREPARATION OF TETRAHYDRO-THIENO3,2-C!- AND 2,3-C!PYRIDINE DERIVATIVES. This invention relates to a process for the preparation of tetrahydro-thieno 3,2-c!pyridine derivatives of the formula (Ia) and their isomeris tetrahydro-thieno 2,3-c!pyridine derivatives in which R1 represents hydrogen, a lower alkyl or alkoxy radical, an aryl radical or an aralkyl radical; R2 and R3 represent hydrogen, halogen, a lower alkyl or alkoxy group, a di(loweralkyl)amino, nitro, cyano or acetamido group or, together with the phenyl nucleus to which they are attached, form a polycyclic aromatic ring, comprising reacting a tetrahydrothieno3,2-c!pyridine derivative of the formula: (IIa) or a derivative of its isomer, tetrahydro2,3-c!pyridine, with formaldehyde H-CHO and a phenol of the formula: (III).nPROCESS FOR THE PREPARATION OF TETRAHYDRO-THIENO¢3,2-C!- AND ¢2,3-C!PYRIDINE DERIVATIVES.
