, p. 361 - 362 (1983)

Two convenient methods for the preparation of p-dialkylaminophenylacetylenes are reported: a) Dehydrobromination of the brominated compounds obtained easily from the dialkylamino substituted cinnamic acids in acetic acid instead of chloroform; b) dehydrochlorination of the 2-chlorostyrene derivative obtained from the reaction of p-dimethylaminobenzaldehyde with chloromethylenetriphenylphosphorane.
