To a solution of the title C compound, [2-(3-methoxy-propoxy)-4-methyl-phenyl]-methanol (300 mg, 1.4 mmol) in 5 mL of chloroform is added trimethylbromosilane (0.28 mL, 2.1 mmol), with stiffing at room temperature. After 2 h the solvent is evaporated off and the crude residue is purified by flash column chromatography on silica gel (hexane/EtOAc 1/1) to afford the title compound as a colorless oil (0.4 g). Rt (HPLC, Nucleosil C18, 10:90-100:0 CH3CN/H2O+0.1% TFA within 5 min, then 100% CH3CN+0.1% TFA): 4.70 min.
