Product 1

HCID 27719705-(4-chlorophenyl)furan-2-carbonyl Chloride

Procedure

A mixture Of 56 g. (0.25 mole) Of 5-(p-Chlorophenyl)-2furoic acid and 100 ml. of SOCl2 is refluxed for 31/2 hours so that HCl gas evolves and there is dissolution. The SOCl2 is removed on a rotary evaporator. Benzene is added to the solid residue and is then removed on the rotary evaporator to give 5-(p-chlorophenyl)-2-furoyl chloride
