134272-64-3, To a solution of 1-(2-aminoethyl)-1H-pyrrol-2,5-dione 2,2,2-hydrochloride: (150mg, 0.849mmol) and TEA (350muL, 2.50mmol) in THF (4mL) was added (E)-perfluorophenyl 4-(phenyldiazenyl)benzoat 7 (666mg, 1.70mmol) in THF (4mL) dropwise. After 16h at rt, the solvent was evaporated, the resulting residue was dissolved in CHCl3 and washed with H2O (30mL), 1M HCl (30mL) and brine (30mL). The organic layer was dried over Na2SO4, filtered and concentrated. The crude product was purified by silica column (eluent EtOAc:hexane: 1:4?1:1; Rf:0.10?0.50) to yield the product as an orange solid (243mg; 82%). 1H NMR (500MHz, DMSO) delta 8.73 (t, J=6.0Hz, 1H), 7.96-7.88 (m, 6H), 7.67-7.56 (m, 3H), 7.01 (s, 2H), 3.62 (t, J=5.7Hz, 2H), 3.45 (dd, J=11.6, 5.9Hz, 2H); 13C NMR (126MHz, DMSO) delta 171.04, 165.76, 153.24, 151.89, 136.61, 134.51, 131.92, 129.49, 128.35, 122.67, 122.27, 37.71, 37.10; HPLC/MS (tr=13.92min; ESI) found: 349.1 (M+H)+, calc.: 349.1.
134272-64-3 N-(2-Aminoethyl)maleimide Hydrochloride 22118207, apyrrolines compound, is more and more widely used in various fields.
