Definitions
- the present invention relates to a new process for the preparation of thieno [2,3-c] and thieno [3,2-c] pyridines of formulas: in which R represents hydrogen or the carboxy group.
- R represents hydrogen or the carboxy group.
- the object of the present invention is to provide an inexpensive synthesis process making it possible to obtain, with good yields, the compounds (I) and (II) which are important intermediates in the chemical and pharmaceutical industry, in particular for the preparation of thienopyridine derivatives having various therapeutic activities, for example anti-inflammatory, anti-platelet aggregation, anti-arrhythmic, etc. (see for example the patents and published French patent applications No. 2 215 948, 2 257,271, 2,315,274 and 2,345,150.
- the process of the invention is characterized in that a compound of formula is reacted with nitrous acid, thus obtaining compounds of formula and reacting the compounds of formula (V) or (VI) respectively with an acid, thereby obtaining the derivatives of formula (I) and (II) respectively in which R is hydrogen, or with an alkali metal hydroxide and subsequent neutralization, thereby obtaining the derivatives of formula (I) and (II) respectively in which R is the carboxy group.
- nitrous acid is formed in situ by reacting an alkali metal nitrite in aqueous solution with an acid.
- the reaction is carried out in particular by slowly adding an aqueous solution of alkali metal nitrite, in particular sodium, to a hydrochloric solution, maintained at 0 ° -15 ° C., of the derivative of formula (III) or (IV) then leaving for several hours at room temperature.
- alkali metal nitrite in particular sodium
- a mineral acid such as hydrochloric acid, hydrobromic acid or sulfuric acid, preferably hydrochloric acid
- an organic acid such as trifluoroacetic acid or trichloroacetic acid, preferably trifluoroacetic acid
- the starting compounds of formula (III) or (IV) can be prepared by reaction of a compound of formula with formaldehyde in aqueous solution, in the presence of a strong acid.
- Example 3 By operating as in Example 3, starting from the nitrose compound obtained in Example 1, thieno [2,3-c] pyridine is obtained. F ⁇ 50 ° C, yield: 47%.
