77095-51-3, Benzofuran-6-carboxylic acid is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
77095-51-3, Benzofuran-6-carboxylic acid (50.0 g, 0.308 moles), toluene and a catalytic amount of dimethyl formamide (DMF) are added, in sequence, to a reactor in N2 atmosphere. The suspension is heated under stirring to 55¡À5C. SOCl2 (0.370 moles) dissolved in toluene is added slowly, maintaining the temperature at 55¡À5C until conversion is complete. The solution is then concentrated under vacuum until an almost solid yellow residue is obtained. Residue = 55.6 g, molar yield = quantitative. ?HNMR (300MHz, CDC13): d 8.32 (s,lH), 8.01 (dd,l H,J;=8.3 l Hz J2=l .34Hz), 7.87 (d, 1 H, =2.08 Hz), 7.69 (d, 1 H, J=8.31 Hz), 6.88 (br d, 1 H).
As the paragraph descriping shows that 77095-51-3 is playing an increasingly important role.
