Adding a certain compound to certain chemical reactions, such as: 222036-66-0, name is 5-Aminoisoindolin-1-one, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 222036-66-0, SDS of cas: 222036-66-0
A mixture of 3-(8-(5,6-dimethoxypyridin-2-ylamino)imidazo[l ,2-b]pyridazin-6-yl)benzoic acid (100 mg, 0.26 mmol), 5-aminoisoindolin-l-one (38 mg, 0.26 mmol), 1 -methyl- lH-imidzole (84 mg, 1.02 mmol) and EDCI (196 mg, 1.02 mmol) in DMF (3 mL) was stirred for 16 h at room temperature. Ethyl acetate (5 mL) and water (5 mL) were added. The organic layer was separated and the aqueous phase was extracted with ethyl acetate (20 mL). The organic phases were combined and washed with brine (10 mL) then dried over Na2S04. The residue was concentrated and triturated with MeOH (2 mL) to give 3-(8-(5,6-dimethoxypyridin-2-ylamino) imidazo[l ,2- b]pyridazin-6-yl)-N-(l-oxoisoindolin-5-yl)benzamide (26 mg, 20 percent) as a yellow solid. 1H NMR (300 MHz, DMSO): delta 10.68 (s, 1H), 9.97 (s, 1H), 8.61 (s, 1H), 8.52 (s, 1H), 8.44 (s, 1H), 8.24 – 8.08 (m, 4 h), 7.82 – 7.64 (m, 4 h), 7.41 (d, 1H, J = 8.7 Hz), 7.1 1 (d, 1H, J = 8.4 Hz), 4.39 (s, 2H), 4.02 (s, 3H), 3.76 (s, 3H). LC-MS : [M+H]+, 521.9, tR = 1.434 min, HPLC: 96.12 percent at 214nm, 96.79 percent at 254nm, tR = 3.673 min.
