실험 절차

Dichloroacetic acid (0.1 mL, 1.2 mmol) was added to a mixture of compound 10 (304 mg, 0.6 mmol), benzyltriethyl ammonium bromide (492 mg, 1.8 mmol) and sodium nitrite (828 mg, 12 mmol) in dibromomethane (10 mL). The mixture was stirred at room temperature for 18 hours in the dark. The reaction mixture was then concentrated and the resulting residue was purified by column chromatography (95% dichloromethane/5% methanol) to afford 80 mg, 24% yield of 4-[2-(5-bromo-4-[7-methoxy-4-methylnaphthalen-1-yl]-4H-1,2,4-triazol-3-ylthio)acetamido]-3-chlorobenzoic acid (11).
