実験手順
The title compound was prepared by the treatment of 5-bromo-2-isopropoxy-benzaldehyde (3.5 gm, 0.014 mol) with copper(I) cyanide (2.5 gm, 0.028 mol) in refluxing DMF for 28 hours. The cooled mixture was poured into a mixture of water (100 mL) and ethyl acetate (100 mL). The mixture was filtered through a pad of Celite, the organic layer separated, washed with saturated brine solution, dried (Na2SO4), and evaporated. The title compound was purified by flash chromatography eluting with 15% ethyl acetate in hexane; yield 1.9 gm of a white solid.
