COA of Formula: C10H9NO3,You could be based in a pharmaceutical company, working on developing and trialing new drugs; or in a public-sector research center, helping to ensure national healthcare provision keeps pace with new discoveries.
Sodium hydroxide solution (1N, 20 ml) was added to a solution of methyl 2-oxoindoline-6-carboxylate (2 g, 10.46 mmol, 1.00 equiv) in methanol (20 ml). The resulting solution was stirred for 2 hours at 80 C. The reaction mixture was cooled to 30 C., diluted with 50 ml of H2O and extracted with 2*30 mL of dichloromethane. The aqueous layers were combined and the pH adjusted to 2 with aqueous hydrochloric acid (6 N). The solids were collected by filtration and dried to give the title product 1.28 g (69%) as a brown solid. 1H NMR (400 MHz, CDCl3) delta: 12.86 (s, 1H), 10.50 (s, 1H), 7.55 (m, 1H), 7.32-7.30 (m, 2H), 3.56 (s, 2H).
The synthetic route of 14192-26-8 has been constantly updated, and we look forward to future research findings.
