272-49-1, 4-Azaindole is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 118; 2-(3-Fluoro-phenyl)-pyrimidine-5-carboxyric acid pyrrolor3,2-b1pyridin-l-vlamide; Step 1 : A solution of pyrrolo[3,2-b]pyridine (1.64 mmol) and potassium tert-butoxide (3.29 mmol) in DMF (7.3 mL) is stirred at rt under N2 for 2 h. 0.15 M NH2CLm ether (16.3 mL) is added drop-wise at rt and the reaction mixture is stirred at rt for 3 h. The reaction mixture is quenched with 5 percent Na2S2O3 aqueous solution (10 mL), and extracted with ether. The combined organic layer is washed with brine, dried (Na2SO4), filtered and concentrated in vacuo. The residue is purified by silica gel chromatography eluting with EtOAc to afford pyrrolon .2-blpyridin- 1 -ylamine (136 mg, 62percent) as a solid. MS: 134 (M+H); 1H NMR (300 MHz, CDCl3): delta 4.89 (br, 2N-H), 6.61 (d, H), 7.16 (m, H), 7.38 (d, H), 7.76 (d, H), 8.47 (d, H)., 272-49-1
272-49-1 4-Azaindole 9226, aindole-building-block compound, is more and more widely used in various.
