Reaction Steps

Dichloroacetic acid (0.35 mL, 4.2 mmol) was added to a mixture of compound 6 (1.04 g, 2.1 mmol), benzyltriethyl ammonium bromide (1.65 g, 6.1 mmol) and sodium nitrite (2.9 g, 42.1 mmol) in dibromomethane (44 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 393 mg, 34% yield of 4-(2-(5-bromo-4-(4-cyclopropylnaphthalen-1-yl)-4H-1,2,4-triazol-3-ylthio)acetamido)-3-chlorobenzoic acid (7).
