Versuchsvorschrift

Sodium hydride (60% in oil, 60 mg, 1.5 mmol) was added portionwise to a solution of 4-bromophenethyl alcohol (0.718 g, 3.57) in THF (6 mL) at 0° C. The reaction mixture was cooled to −40° C., and a solution of 16G (0.550 g, 1.19 mmol) in THF (5 mL) was added slowly dropwise. The reaction mixture was slowly warmed to 0° C., and then stirred for 3 h at 0° C. The reaction mixture was diluted with water and extracted with ethyl acetate. The combined organic layers were washed with water and brine, dried (MgSO4) and concentrated in vacuo. The residue was purified by silica gel chromatography (gradient from 0 to 50% ethyl acetate in hexanes) to give 16H (0.503 g, 74%) as a white solid.
