4-Methoxyphenylacetyl chloride → HCID 20370079, compound

Participants

Reaction Steps

Repeating the procedure of Example 1 but replacing the p-thiomethylphenyl acetyl chloride with an equivalent amount of p-methoxyphenyl acetyl chloride, there is similarly obtained ethyl 4-(p-methoxyphenyl)-2-methyl-buta-2,3-dienoate, which when treated according to the procedure of Example 2, yields 4-(p-methoxyphenyl)-2-methyl-buta-2,3-dienoic acid (m.p. 105° - 108° from ether/pentane).
