Carbon Tetrachloride → N-(4-Benzyloxy-phenyl)-2,2,2-trifluoro-acetimidoyl chloride

Participants

Reaction Steps

A mixture of resin-supported triphenylphosphine (3 mmol triphenylphosphine/g resin; 58.6 g) and N-(4-benzyloxy-phenyl)-2,2,2-trifluoro-acetamide in carbon tetrachloride (800 ml) was heated to reflux under nitrogen for 18 h. The mixture was allowed to cool then filtered, washing the resin with dichloromethane (1l) and ether (1l). The organics were concentrated in vacuo to give the title compound as a yellow solid (20.7 g). T.l.c. (Cyclohexanelethyl acetate (9:1)) Rf 0.81
