Thiocolchicine (II) was prepared from colchicine (I) by treatment with sodium methylthiolate. Then, hydrolysis of acetamide group with methanolic HCl afforded deacetyl thiocolchicine (III). Subsequent acylation with p-nitrobenzoyl chloride (IV) in the presence of pyridine provided amide (V), which was demethylated with excess BBr3 to give the corresponding triphenol.
