With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.134272-64-3,N-(2-Aminoethyl)maleimide Hydrochloride,as a common compound, the synthetic route is as follows.
A solution of 14.6 mM DM4 in DMA (2 mL, 29.2 mmol) was treated with 1:1 solution of saturated sodium bicarbonate to water (5%, 219 tl) followed by Sulfo-SPDB (29.7 mg, 0.073 mmol) under argon at room temperature with HPLC/MS monitoring. After 1 hour DM4 was consumed to give DM4-Sulfo-SPDB-DM4. Low Resolution MS calcd. (M1)= 1073.2; found (M-1)=1073.2.The reaction was treated with 1-(2-aminoethyl)-maleimide HC1 (12.90 mg, 0.073 mmol) under argon. After 3 hour desired product was formed. The material was purified on semi-prep HPLC C8 column using Water with 0.2% fomiic acid and 0.1% TEA and Acetonitrile. Low resolution MS, calcd. (M-1)=1098.34; found (M-1)=1098.2.
134272-64-3 N-(2-Aminoethyl)maleimide Hydrochloride 22118207, apyrrolines compound, is more and more widely used in various.
