Zhang, Jun published the artcileSynthesis of m-aminophenyl acetylene, Name: (E)-3-(3-Nitrophenyl)acrylic acid, the publication is Zhongguo Yiyao Gongye Zazhi (2012), 43(10), 812-814, database is CAplus.
M-Aminophenyl acetylene, the key intermediate of antitumor agent erlotinib hydrochloride, was synthesized from m-nitrobenzaldehyde by Perkin reaction, bromine addition, elimination of hydrogen bromide and decarboxylation to give (Z)-1-bromo-2-(3-nitrophenyl)ethylene, followed by reaction with NaH and reduction with Fe/HCl. The overall yield was about 45%.
Zhongguo Yiyao Gongye Zazhi published new progress about 1772-76-5. 1772-76-5 belongs to catalysis-chemistry, auxiliary class Benzenes, name is (E)-3-(3-Nitrophenyl)acrylic acid, and the molecular formula is C9H9BrO2, Name: (E)-3-(3-Nitrophenyl)acrylic acid.
