(0436) (0437) To a suspension of the free thiol, 3a (88 mg, 0.105 mmol) and 1-((2,5-dioxopyrrolidin-1-yl)oxy)-1-oxo-4-(pyridin-2-yldisulfanyl)butane-2-sulfonic acid (64.0 mg, 0.158 mmol) in anhydrous dichloromethane (2.10 mL) was added DIPEA (55.0 muL, 0.315 mmol) under nitrogen at room temperature. The mixture stirred for 16 hours and then 1-(2-aminoethyl)-1H-pyrrole-2,5-dione hydrochloride (55.6 mg, 0.315 mmol), anhydrous dichloromethane (1.0 mL) and DIPEA (0.055 mL, 0.315 mmol) were added. The mixture stirred for an additional 5 hours at room temperature upon which the reaction was concentrated in vacuo. The resulting residue was purified by RP-HPLC (C18, CH3CN/H2O). Fractions containing desired product were frozen and lyophilized to give maleimide, compound D3 (20 mg, 16% yield) as a white solid. LCMS=4.92 min (8 min method). MS (m/z): 1158.6 (M+1)+.
134272-64-3, 134272-64-3 N-(2-Aminoethyl)maleimide Hydrochloride 22118207, apyrrolines compound, is more and more widely used in various fields.
