4.2 1 6-Bromohexadecan- 1 -ol10215] The diol 14 (1.047 g, 4.05 mmol) was dissolved in cyclohexane (30 mE) and vigorously stirred with 48% HBr (0.5 mE, 4.46 mmol, 1.1 eq.). The mixture was refluxed for 6 h, diluted with water (50 mE) and the phases were separated. The aqueous phase was extracted with a mixture of dichloromethane and methanol (v/v, 4:1 3×20 mE). The combined organic layer was dried over Mg504. The product was purified by column chromatography with silica gel (6×6 cm, cyclohexane/ethyl acetate, 8:1) and isolated as a white solid. Yield: 4.598 g (96%). Traces of i,i6-dibromohexadecane were also found.1515 13 11 9 7 5 3 1j0216] M.p.: 65 C.
