Reaction Steps

A solution of (3-oxo-1,3-dihydro-2-benzofuran-1-yl)acetonitrile (890 mg, 5.14 mmol) and azidotributyltin (1.97 ml, 7.20 mmol) in dioxane (4.0 ml) was heated at 95° C. for 17 hours. The reaction was partitioned between EtOAc and saturated NaHCO3 aqueous solution, and then washed with saturated NaHCO3 aqueous solution. The aqueous layers were combined, washed with EtOAc, then acidified with 10% HCl aqueous solution. The acidic aqueous layer was extracted with EtOAc. The combined organic layers were then washed with brine, dried with anhydrous Na2SO4, and rotary evaporated to obtain a yellow oil. The oil was dissolved in CHCl3/Hexane and allowed to crystallize, leading to 3-(1 H-tetrazol-5-ylmethyl)-2-benzofuran-1(3 H)-one as a white solid (913 mg, 82%).
