40047-23-2, 6-Hydroxyindole-2-carboxylic acid is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A solution of A (500 mg, 1.61 mmol) and 221-1 (286 mg, 1.61 mmol) and K2CO3 (446 g, 3.23 mmol) in DMSO (4 mL) is heated for 2 h at 140 ¡ãC and 10 h at 150 ¡ãC. The reaction is poured into H2O, extracted thrice with EtOAc, washed thrice with saturated aqueous NaHCO3, dried over Na2SO4, filtered and concentrated to give 221-2. The aqueous phase is acidified with concentrated HCl and extracted four times with EtOAc, washed with H20, dried over Na2SO4, filtered and concentrated to provide additional 221-2.
40047-23-2, As the paragraph descriping shows that 40047-23-2 is playing an increasingly important role.
