Reaction Steps

Allyl bromide (0.27 ml, 3.13 mmol) and cesium carbonate (1.02 g, 3.13 mmol) were added to a solution of the obtained compound in N,N-dimethylformamide (5 ml), and the mixture was stirred at room temperature for 1 hour. After water was added to the reaction mixture and the mixture was extracted with ethyl acetate, the organic layer was washed with a saturated aqueous NaCl solution and dried with anhydrous sodium sulfate. The residue obtained by removing the solvent under reduced pressure was purified by silica gel column chromatography (developing solvent: hexane/ethyl acetate=2/1) to give a mixture of 1-allyl-5-(4′-methoxymethoxy-1,1′-biphenyl-4-yl)-1H-tetrazole and 2-allyl-5-(4′-methoxymethoxy-1,1′-biphenyl-4-yl)-2H-tetrazole (504 mg, two-step total yield: 71%).
