Методика

Cycloheptylmethanol was coupled with 3-bromophenol following the method used in Example 10. After concentration under reduced pressure, hexanes was added. The mixture was stirred and sonicated then the precipitate was removed by filtration and the solids washed with hexanes. The combined filtrates were concentrated under reduced pressure. Purification by flash chromatography (10 to 50% EtOAc-hexanes gradient) gave ((3-bromophenoxy)methyl)cycloheptane. (Yield 1.0697 g, 56%): 1H NMR (400 MHz, CDCl3) δ 7.12 (t, J=8.4, 1H), 7.06-7.04 (m, 2H), 6.82 (dq, J=8.0, 1.2, 1H), 3.70 (d, J=6.4, 2H), 1.91-1.98 (m, 1H), 1.81-1.88 (m, 2H), 1.42-1.72 (m, 8H), 1.24-1.34 (m, 2H).
