Procedure

To a stirred solution of (E)-5-phenylpent-3-en-1-ol (Preparation example 236, 6.3 g, 38.83 mmol) in CH2Cl2 was added imidazole (3.4 g, 50.48 mmol) and TBDMS-Cl (7.6 g, 50.48 mmol) at 0° C. then stirred for 1 h at room temperature. The resulting mixture was diluted with EtOAc, washed with water, dried over MgSO4, filtered, and concentrated under reduced pressure. The crude compound was purified by a silica gel column to produce the title compound (10.6 g, 80˜98%)
