Methyl iodide → 2-Hydroxy-4-methoxybenzophenone

참여 물질

반응 단계

The above prepared (2,4-dihydroxy-phenyl)-phenyl-methanone (0.775 g, 3.62 mmol) was dissolved in 15 mL of acetonitrile and treated successively at 0° C. with Cs2CO3 (1.297 g, 1.1 eq.) and iodomethane (0.242 mL, 1.08 eq.), and the mixture was then stirred over night at ambient temperature. Pouring onto crashed ice/NH4Cl, twofold extraction with AcOEt, washing with water, drying over sodium sulfate, and evaporation of the solvents, followed by flash chromatography (SiO2, heptane/AcOEt=9/1), delivered 0.681 g of the title compound as off-white oil.
