Application of 141452-01-9, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 141452-01-9, name is Methyl indoline-5-carboxylate, This compound has unique chemical properties. The synthetic route is as follows.
Preparation of Compound 113, 6-(pyridin-2-ylmethoxy)nicotinic acid[00135] LiOH (1 .345 M, 0.615 mL, 0.827 mmol) was added to a solution ofCompound 1 12 (0.101 g, 0.414 mmol) in THF (2 mL), followed by MeOH (0.6 mL) and the reaction mixture was stirred at rt for 26 h, concentrated to remove organic solvents, diluted with water, and washed with EtOAc (1 x). The aqueous phase was acidified to pH 2-3 with 2 M HCI, and the resulting precipitate was isolated by filtration, washed with water and dried to afford the title compound (79 mg, 83%) as a white solid.1H NMR (500 MHz, DMSO) 5 13.07 (s, 1 H), 8.71 (dd, J = 2.5, 0.8 Hz, 1 H), 8.56 (ddd, J = 5.0, 1 .8, 1 .1 Hz, 1 H), 8.19 (dd, J = 8.6, 2.4 Hz, 1 H), 7.81 (td, J = 7.7, 1 .7 Hz, 1 H), 7.46 (br d, J = 7.8 Hz, 1 H), 7.34 (ddd, J = 7.6, 4.8, 1 .1 Hz, 1 H), 7.04 (dd, J = 8.6, 0.8 Hz, 1 H), 5.50 (s, 2H). HRMS (ESI+): calcd for C12H11N2O3 (M + H)+, 231 .0764; found 231 .0760.
The chemical industry reduces the impact on the environment during synthesis Methyl indoline-5-carboxylate. I believe this compound will play a more active role in future production and life.
