Simple exploration of 7169-34-8

As the paragraph descriping shows that 7169-34-8 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.7169-34-8,Benzofuran-3(2H)-one,as a common compound, the synthetic route is as follows.,7169-34-8

General procedure: A mixture of benzofuran-3(2H)-one (2.0 mmol), benzaldehyde (2.2mmol) and water (5 mL) was stirred at reflux temperature for 6-10 h. Completion of the reaction was checked on TLC. Then the mixture was allowed to rt and stirred for 1 h. The precipitated solids were filtered, washedwith water (2 ¡Á 5 mL) and dried to give the product. (Z)-2-Benzylidenebenzofuran-3(2H)-one (4a). Pale yellow color solid (380 mg, 86%), mp 102-104 C (lit.23 mp110-111 C). 1H NMR (CDCl3): 7.93 (2H, d, J 6.8 Hz), 7.82 (1H, d, J 7.6 Hz), 7.66 (1H, t, J 8.2 Hz), 7.38-7.48 (3H,m), 7.34 (1H, d, J 8.0 Hz), 7.22 (1H, t, J 7.4 Hz), 6.90 (1H, s); 13C NMR (CDCl3): 184.7, 166.2, 146.9, 136.8, 132.4,131.5, 129.9, 128.9, 124.7, 123.5, 121.7, 113.0, 112.9; LC-MS (positive ion mode): m/z 223 (M+H)+.
