2882-15-7, 5-Methoxy-2-methyl-3-indoleacetic acid is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
5-(((5-Methoxy-2-methyl-1H-indol-3-carbonyl)amino)methyl)-2-(oxalyl-amino)-4,7-dihydro-5H-thieno[2,3-c]pyran-3-carboxylic acid; To a solution of 5-methoxy-2-methyl indole-3-acetic acid (0.26 g, 1.18 mmol), and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide, hydrochloride (0.27 g, 1.4 mmol) in acetonitrile (10 ml) was added triethylamine (0.46 ml, 3.2 mmol). The reaction mixture was allowed to stir for 10 min at room temperature before compound 2-amino-5-aminomethyl-4,7-dihydro-5H-thieno[2,3-c]pyran-3-carboxylic acid tert-butyl ester (0.307 g, 1.08 mmol) was added. The reaction mixture was allowed to stir for 18 hours and then concentrated in vacuo. Ethyl acetate and water were added and the layers separated. The organic layer was washed with hydrochloric acid (0.5M, (v/v)), saturated sodium bicarbonate (2¡Á25 ml) and brine (2¡Á25 ml). The organic layer was dried (MgSO4), filtered and concentrated in vacuo. The crude 2-amino-5-(((5-methoxy-2-methyl-1H-indol-3-carbonyl)amino-methyl)-4,7-dihydro-5H-thieno[2,3-c]pyran-3-carboxylic acid tert-butyl ester was used immediately in the next step.1H-NMR (CDCl3) delta 7.90 (bs, 1H), 7.19 (d, 1H, J=8.8 Hz), 6.87 (d, 1H, J=2.4 Hz), 6.79 (dd, 1H, J=8.8 Hz and J=2.4 Hz), 6.18 (m, 1H), 5.94 (s, 2H), 4.33 (m, 2H, J=25 Hz, J=14 Hz, J=2.8 Hz and J=1.6 Hz), 3.80 (s, 3H), 3.76 (ddd, 1H, J=14 Hz, J=8 Hz and J=2.8 Hz), 3.65 (s, 3H), 3.53 (m, 1H), 2.99 (ddd, 1H, J=13 Hz, J=5.6 Hz and J=4 Hz), 2.76 (dt, 1H, J =16.8 Hz, J=2.8 Hz), 2.42-2.40 (m, 1H), 2.38 (s, 3H), 1.51 (s, 9H).
As the paragraph descriping shows that 2882-15-7 is playing an increasingly important role.
