| titleOfInvention | Preparation of thieno-imidazole derivatives |
| abstract | A process for the preparation of a thieno-imidazole derivative having the general formula:-werein R is -(CH<sub>2</sub>)<sub>4</sub>CH<sub>3</sub>, -(CH<sub>2</sub>)<sub>3</sub>OR<sup>1</sup> or -(CH<sub>2</sub>)<sub>5</sub>0R<sup>1</sup>, R' is (C<sub>1</sub>-C<sub>6</sub>) alkyl, -(CH<sub>2</sub>)<sub>4</sub>CN or -(CH<sub>2</sub>)<sub>4</sub>COOR<sup>2</sup> and R<sup>2</sup> is (C<sub>1</sub>-C<sub>6</sub>) alkyl or phenyl; characterized in that a compound of the formula:-wherein R is as defined above, is reacted with an epoxy compound of the formula:-wherein R<sup>3</sup> is hydrogen, methyl or-CH<sub>2</sub>OH; in the presence of an alkanol.In particular this process may be used to prepare descarboxybiotin which is a useful intermediate for the preparation of d - biotin. |
