Versuchsvorschrift

(E)-3-(4-fluoro-3-methoxyphenyl)-2-(4-isopropoxyphenyl)acrylic acid (4.38 g, 13.26 mmol), (PhO)2PON3 (2.71 mL, 12.60 mmol), and Et3N (3.70 mL, 26.5 mmol) were dissolved in benzene and stirred for 16 h. The solution was concentrated under vacuum and the residue was purified by silica gel chromatography using 20% EtOAc/Hexanes to give (E)-3-(4-fluoro-3-methoxyphenyl)-2-(4-isopropoxyphenyl)acryloyl azide (2.3 g, 49% yield). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 7.80 (s, 1H), 7.16-7.11 (m, 2H), 6.97-6.92 (m, 2H), 6.84-6.78 (m, 1H), 6.63-6.53 (m, 2H), 4.63-4.54 (m, 1H), 3.49 (s, 3H), 1.38-1.35 (m, 6H).
