Reaction Steps

Benzyl piperazine-1-carbamate (2.203 g, 10.0 mmol) was dissolved in tetrahydrofuran (50 ml); 2-hydroxy-2-methylpropionic acid (1.25 g, 12.0 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (2.30 g, 12.0 mmol), 1-hydroxy-1H-benzotriazole monohydrate (1.84 g, 12.0 mmol) and triethylamine (3.35 ml, 24.0 mmol) were added; and the reaction mixture was stirred at room temperature for 7 hours. The reaction mixture was partitioned between ethyl acetate and 1N hydrochloric acid. The organic layer was washed with water, a saturated aqueous solution of sodium hydrogencarbonate and brine, and dried over anhydrous sodium sulfate. The solvent was distilled off, and dried under reduced pressure to yield the title compound (2.823 g, 9.21 mmol, 92.1%) as a colorless oil.
