Adding a certain compound to certain chemical reactions, such as: 41910-64-9, name is 4-Chloroindoline, 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 41910-64-9, name: 4-Chloroindoline
Example 28b Synthesis of 2-[2-(4-chloro-2,3-dihydroindol-1-yl)-2-oxoethyl]-6-(2-methylmorpholin-4-yl)-3H-pyrimidin-4-one 0.975 g of the sodium salt of [4-(2-methylmorpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetic acid (example 1b, step 2b), 0.534 g of 4-chloroindoline, 0.57 ml of pyridine and 15 ml of DMF are placed in a round-bottomed flask, and then 0.9 g of N-[3-(dimethylamino)propyl]-N?-ethylcarbodiimide hydrochloride is added. The reaction mixture is stirred at ambient temperature for 72 hours. The reaction mixture is poured into 50 ml of water, with stirring, and then the solid formed is filtered off through sintered glass and washed 3 times with approximately 15 ml of water, washed with 10 ml of EtOAc and rinsed with twice approximately 5 ml of diisopropyl ether, and the resulting product is left to air-dry under a hood. 2-[2-(4-Chloro-2,3-dihydroindol-1-yl)-2-oxoethyl]-6-(2-methylmorpholin-4-yl)-3H-pyrimidin-4-one is isolated (0.98 g) and characterized in the form of an off-white solid (yield 71%).LCMS ES+DMSO Tr 1.15; MH+m/z=389Mass Spectrometry:The spectra were obtained on a Waters UPLC-SQD apparatusIonization: positive and/or negative mode electrospray (ES+/-)Chromatographic Conditions: Column: Acquity BEH C18-1.7 mum-2.1¡Á50 mm Solvents: A: H2O (0.1% formic acid) B: CH3CN (0.1% formic acid) Column temperature: 50 C. Flow rate: 1 ml/min Gradient (2 min): from 5 to 50% of B in 0.8 min; 1.2 min: 100% of B; 1.85 min: 100% of B; 1.95: 5% of BAnalytical Results:Retention time Tr (min)=0.82; [M+H]+: m/z 389; [M-H]-: m/z 3871H NMR spectrum (400 MHz): 1.06 (d, J=6.4 Hz, 3H); 2.48 (partially masked m, 1H); 2.80 (m, 1H); 3.19 (t, J=8.7 Hz, 2H); 3.40 to 3.50 (m, 2H); 3.76 (s, 2H); 3.81 (dd, J=3.0 and 11.5 Hz, 1H); 3.93 (m, 1H); 4.03 (m, 1H); 4.20 (t, J=8.7 Hz, 2H); 5.22 (s, 1H); 7.09 (d, J=8.1 Hz, 1H); 7.22 (t, J=8.1 Hz, 1H); 7.97 (d, J=8.1 Hz, 1H); 11.61 (broad s, 1H)
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Chloroindoline, other downstream synthetic routes, hurry up and to see.
