Reaction Steps

6-(2-Imidazolinylamino-7-methyl-2,3-dihydrobenzofuran hemiacetate. The above crude 6-[N'-(2-aminoethyl)thioureido]-7-methyl-2,3-dihydrobenzofuran is dissolved in 3 mL of methanol and treated with 0.25 g of mercuric acetate, forming a black color. The reaction mixture is stirred overnight at room temperature. The reaction mixture is filtered through celite, concentrated, and purified by silica gel chromatography to provide 0.131 g of 6-(2-imida zolinylamino)-7-methyl-2,3-dihydrobenzofuran as the hemiacerate salt.
