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, category: indolines-derivatives
p-TSA monohydrate (23.12 mg, 0.122 mmol) was added to a stirred solution of 1-(4-((2-chloropyrimidin-4-yl)oxy)naphthalen-1 -yl)-3-(1 -(p-tolyl)-3-(tri methylsi lyl)-1 H-pyrazol-5-yl)urea (see Example 6(i) above; 33 mg, 0.061 mmcl) and 5-aminoisoindolin-1-one (18.01 mg, 0.122 mmol) in THFDMF (1 mL, 1:1). The resulting mixture was heated at 60 °C overnight. The reaction was cooled to rt then diluted with EtOAc (15 mL). The suspension was filtered, the product was detected in the filtrate which was subsequentlyconcentrated in vacuo. The crude product was purified by chromatography on silica gel (12 g column, 0-10percent MeOH in DCM) to afford a white solid. The crude product was purified by preparative HPLC (Waters, Acidic (0.1percent Formic acid), Waters X-Select PrepC18, 5 pm, 19×50 mm column, 35-75percent MeCN in Water) to afford the title compound (7 mg) as a white solid.1H NMR (DMSO-d6) 400 MHz, O: 9.93 (s, 1H), 9.24 (s, 1H), 8.84 (s, 1H), 8.47 (d, 1H),8.22 (s, 1H), 8.11 (d, 1H), 8.00 (d, 1H), 7.82-7.80 (m, 1H), 7.65-7.61 (m, 1H), 7.58-7.54(m, 1H), 7.53-7.36 (m, 6H), 7.34-7.25 (m, 2H), 6.70 (d, 1H), 6.65 (s, 1H), 3.99 (s, 2H),2.41 (s, 3H), 0.27 (s, 9H).LCMS mz 655 (M+H)+ (ES+).
