反応手順
A mixture of 3,5-dichlorobenzyl alcohol (Aldrich, 25 g), thionyl chloride (100 ml) and DMF (0.5 ml) was stirred and refluxed for 4 hours. After cooling the mixture was concentrated in vacuo, the residue was taken up in ether, washed with saturated aqueous NaHCO3 and brine, dried (MgSO4) and concentrated in vacuo to give 3,5-dichlorobenzyl chloride as a light yellow solid, which was used without further purification, 28 g, mp. 32°-36° C.
