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
