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. 40314-06-5, name is 5-Methylisoindoline-1,3-dione, This compound has unique chemical properties. The synthetic route is as follows., HPLC of Formula: C9H7NO2
Isovaleryl chloride (0.50 mL, 4.1 mmol) was added to a mixture of 4-methylphthalimide (0.78 g, 4.8 mmol), triethylamine (0.86 mL, 6.2 mmol), and acetonitrile (8.2 mL) at room temperature and with stirring. After 24 h, the mixture was diluted in EtOAc and washed with satd aq NaHCO3 and brine. The organic phase was dried (MgSO4) and concentrated. The crude material was purified by flash chromatography (SiO2, hexanes:EtOAc 4:1) to give 10 (713 mg, 2.91 mmol, 71%) as a white solid. 1H NMR (300 MHz, CDCl3): delta 7.83 (d, J=7.7Hz, 1H), 7.74 (s, 1H), 7.65 (d, J=7.6Hz, 1H), 2.90 (d, J=6.9Hz, 2H), 2.57 (s, 3H), 2.25 (septet, J=6.7Hz, 1H), and 1.03 (d, J=6.7Hz, 6H). 13C NMR (75 MHz, CDCl3): delta 171.6, 165.6, 165.5, 147.1, 136.2, 131.4, 128.5, 124.6, 124.3, 47.4, 25.0, 22.4, and 22.1. IR (neat): 2956, 1750, 1711, 1612, 1364, 1309, 1109, 1047, and 738 cm-1. HRMS: Calcd for C14H15NNaO3+ [M+Na+] requires 268.0944; found 268.0945. Mp: 180-186 C.
