반응 단계
Ueno et al. (U.S. Pat. No. 6,340,759) also describe a two-step procedure for preparing p-(2-hydroxyethoxy)styrene starting with p-hydroxybenzaldehyde. In the first step, p-(2-hydroxyethoxy)benzaldehyde is formed by reacting p-hydroxybenzaldehyde, sodium hydride, and (2-bromoethoxy)-tert-butyldimethylsilane. In the second step, p-(2-hydroxyethoxy)styrene is formed by reacting the isolated p-(2-hydroxyethoxy)benzaldehyde with (ethyl)triphenylphosphonium bromide in the presence of sodium hydride.
