Excess acetamidine hydrochloride is condensed with α-dimethoxy-β-methoxypropionitrile in an alkaline (methanol and sodium methanol) medium to 3,6-dimethyl-1,2-dihydro-2,4,5,7-tetraazanaphthalene, which is then hydrolysed at 98-100°C, then ring-opened to form 2-methyl-4-amino-5-aminomethylpyrimidine in alkaline conditions; this is followed by interaction with carbon disulphide and ammonia, and then with acetic acid -γ- Chloro-γ-acetylpropyl acetate, then hydrolysed and ring-opened in hydrochloric acid at 75-78°C to form thiosulfamide hydrochloride, and finally thiamine hydrochloride was obtained by neutralisation with ammonia, oxidation with hydrogen peroxide and acidification with hydrochloric acid.
