Reaction Steps

Maleimidoacetic acid (155 mg, 1.0 mmol) in 5 ml of diglyme was treated at 0° C. with N-hydroxysuccinimide (127 mg, 1.1 mmol) and dicyclohexylcarbodiimide (227 mg, 1.1 mmol). After 1 hour at 0° C. and 3 hours at room temperature, the reaction mixture was filtered and evaporated to dryness to yield 0.25 g of crude maleimidoacetic acid N-succinimidyl ester.
