134272-64-3, N-(2-Aminoethyl)maleimide Hydrochloride is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

To a solution of the NHS ester, 6b (12.3 mg, 0.011 mmol) and N-(2- aminoethyl)maleimide hydrochloride (2.0 mg, 0.011 mmol) in anhydrous dichloromethane (0.3 mL) was added DIPEA (0.0022 mL, 0.013 mmol). The mixture was stirred at room temperature for 3 hours then it was stripped under reduced pressure. The residue was purified by semi-preparative reverse phase HPLC (CI 8 column, CH3CN/H2O). The fractions that contained pure product were combined, frozen and lyophilized to give the desired maleimide, compound D6 (10 mg, 80% yield). LCMS = 8.3 min (15 min method). MS (m/z): 1181.8 (M + D+)., 134272-64-3

As the paragraph descriping shows that 134272-64-3 is playing an increasingly important role.
