실험 절차

A mixture of N-(1-tert-butoxycarbonyl-7-fluoro-4-methyl-5-benzimidazolyl)-N'-2-aminoethylthio-urea (0.5 g) and mercuric acetate (0.52 g) in methanol (150 mL) is stirred at room temperature for 1 hour. The resulting black mixture is filtered on Celite with methanol wash of the solids. The filtrate is rotary evaporated and the residue filtered through a short pad of silica gel, eluting 25% methanol in chloroform containing 1% of ammonium hydroxide. The product-containing fractions are rotary evaporated, the residue diluted with water (15 mL), filtered through a plug of glass wool and lyophilized to afford 7-fluoro-4-methyl-5-(2-imidazolinylamino)benzimidazole as a pale yellow solid.
