Versuchsvorschrift

To a stirred solution of (4-methoxy-3-methylphenyl)methanol (2.31g, 15.18mmoles, 1eq) in anhydrous CH2Cl2(50ml, 0.3M) was added hexachloroethane (3.59g, 15.18mmoles, 1eq) and triphenylphosphine (3.98g, 15.18mmoles, 1eq). This mixture was stirred at room temperature overnight at which point the reaction was transferred to a separatory funnel and washed with H2O, brine, dried over Na2SO4, filtered, concentrated in vacuo and filtered through a plug of silica gel (30% EtOAc/Hexanes) to yield 2.59g (100%) of product.
