実験手順

A solution of 4-benzyloxy-2-hydroxyacetophenone (2.45 g), potassium carbonate (3.25 g), potassium iodide (0.42 g), and 5-cyano-5-methyl-1-bromohexane (2.6 g) in dimethylformamide (40 mL) was heated at 90° C. for 22 hours under nitrogen. The slurry was cooled, poured into water (150 mL) and extracted with ethyl acetate. The combined extracts were washed with water, dried (MgSO4), filtered, and concentrated under reduced pressure to an orange oil. This was purified by flash chromatography (ethyl acetate:hexane) to afford the product (2.4 g) as a clear oil. NMR(CDCl3): 1.37, s (6H); 1.64, m (4H); 1.89, m (2H); 2.58, s (3H); 4.03, t (3H); 5.09, s (2H); 6.50, s (1H); 6.58, d (1H); 7.37, m (5 H); 7.81, d (1H). Mass Spec (GC-MS) m/z=365 (M).
