Substituted thiophenes: compositions, processes of making, and uses in disease treatment and diagnosis
The invention provides the process illustrated in scheme 1 for synthesizing heterocyclic compounds of formula I.
1
In the process, an isothiocyanate of formula II is initially reacted with a primary amine of formula III to give a thiourea of formula IV. Subsequently, the thiourea of formula IV is converted to the corresponding heterocycle of formula I using a base and a sulfonyl chloride.

The present invention is an improved process for the preparation of a sodium/proton exchange inhibitor of sub-type 3 (NHE-3) useful in the treatment of sleep apnea and other related respiratory disorders. The improved synthesis of the NHE-3 inhibitor, more specifically a benzimidazol thienylamine, utilizes novel reagents and chemical intermediates and thereby results in an improved yield and purity of the final product with less reaction or synthetic steps required
