To a solution of 2-(tert-butoxycarbonyl(methyl)amino)-2-methylpropanoic acid (5 g), N-hydroxysuccinamide (2.65 g) in DCM (100 mL) was added triethylamine (6.42 mL) and EDC (4.41 g). The reaction mixture was stirred at room temperature overnight. The reaction mixture was washed with sodium bicarbonate (100 mL), dried with magnesium sulfate, filtered and then concentrated to afford 2,5-dioxopyrrolidin-1-yl 2-(tert-butoxycarbonyl(methyl)amino)-2-methylpropanoate as a colourless oil (5.1 g).
