Adding a certain compound to certain chemical reactions, such as: 1029691-06-2, name is 2-(3-Oxocyclopentyl)isoindoline-1,3-dione, 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 1029691-06-2, Recommanded Product: 2-(3-Oxocyclopentyl)isoindoline-1,3-dione
Mix (4-trifluoromethoxy-phenyl)-hydrazine hydrochloride (1.5 g, 6.56 mmol) and (+/-)-2-(3-oxo-cyclopentyl)-isoindole-1,3-dione in EtOH (20 mL) and heat to reflux for 14 hours. Concentrate the reaction mixture in vacuo and dilute the residue with Et2O (150 mL). Place the mixture in an ultrasonic bath for 10 min, then filter off a solid. Concentrate the filtrate to give the crude product. Purify the material on silica gel (120 g) using 10-60% EtOAc/hexanes to give 520 mg (22%) of the title compound as a yellow solid. 1H-NMR (DMSO-d6) delta 11.22 (s, 1H), 7.85 (m, 4H), 7.38 (d, 1H, J=8.8 Hz), 7.28 (d, 1H, J=1.3 Hz), 6.96 (dd, 1H, J=8.8, 1.3 Hz), 5.41 (m, 1H), 3.38-3.11 (m, 4H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-(3-Oxocyclopentyl)isoindoline-1,3-dione, and friends who are interested can also refer to it.
