HCID 28062062',5'-Dichloro-3-dimethylaminoacrylophenone

実験手順

A mixture of 31.0 g of 2',5'-dichloroacetophenone and 25 ml of N,N-dimethylformamide dimethyl acetal is heated on a steam bath for 6 hours, then evaporated to dryness in vacuo. The residue is slurried with hexane, and filtered to give 35.3 g of 2',5'-dichloro-3-dimethylaminoacrylophenone as orange crystals, mp 83°-85° C.
