실험 절차

A suspension of the title B compound, 1-bromo-3-(4-methoxy-but-1-enyl)-benzene (1.8 g, 7.46 mmol) and Pd/c 5% (0.36 g) in THF (20 mL) is shaked under an hydrogen atmosphere. After completion of the reaction, the mixture is filtered through a pad of celite, the solvent is evaporated under reduced pressure and the residue purified by flash chromatography on silica gel (hexane/EtOAc 98/2) to give the title compound as a yellow oil: MS 260.1, 261.9 [M+18]. Rt (HPLC, Nucleosil C18, 10:90-100:0 CH3CN/H2O+0.1% TFA within 5 min, then 100% CH3CN+0.1% TFA): 6.45 min.
