실험 절차
A mixture of 1 g of 4-bromobenzyl bromide, 0.41 g of 1,2,4-triazole, 0.55 g of potassium carbonate and 33 mg of potassium iodide in 30 ml of acetone is stirred for 20 hours at 50°. The solid material is removed by filtration and the solution is concentrated by evaporation. The resulting crude precursor (1) is purified by column chromatography (SiO2, hexane/ethyl acetate 1:1) and crystallised from ether; m.p. 77°-79°; 1H-NMR (CDCl3): δ=5.3 (2H,s), 7.15 and 7.5 (4H,m), 7.95 (1H,s), 8.08 (1H,m).
