Shandong Kwè
Metòd preparasyon: MgCl2 (22.2g, 233.35mmol) ak triethylamine (59.03g, 583.39mmol) yo te ajoute nan solisyon acetonitrile (200ml) brase nan 2-chlorophenol (20.0g, 155.60mmol) nan tanperati chanm. Ajoute poly (chemicalbook fòmaldeyid, 0.52g, 1.05mol) nan melanj lan, ak Lè sa a, rflu pou 4 èdtan. Melanj la ki kapab lakòz refwadi nan tanperati chanm, etenn ak 2nhcl, ekstrè ak etè, seche ak MgSO4, filtre ak konsantre anba presyon redwi. Konpoze brit la te pirifye pa kwomatografi kolòn jèl silica pou jwenn konpoze tit 3-chloro-2-hydroxybenzene.
