4-Hydroxybenzaldehyde → p-((Trimethylsilyl)oxy)benzaldehyde

참여 물질

반응 단계

To a stirred solution of 122 g 4-hydroxybenzaldehyde (1.0 mol, available from Aldrich) and 111 g triethylamine (1.1 mol, available from Aldrich) in 1.0 L dichloromethane was added dropwise 108 g chlorotrimethylsilane (1.1 mol). This mixture was allowed to stand at room temperature for three days before 500 mL hexane was added. The mixture was filtered to remove triethylamine hydrochloride, and most of the solvent was removed at reduced pressure. A 200 mL portion of hexane was then added, the mixture filtered again, and solvent removed at reduced pressure to leave the desired product.
