Participants

Reaction Steps

4.27 g of N-(tert-butoxycarbonyl)aspartic acid-4-benzyl ester and 1.31 mL of n-butyl amine were dissolved in 25 mL of DMF, and then 2.93 g of WSC hydrochloride and 1.93 g of HOBt were added thereto, and the reaction solution was stirred at room temperature overnight. The reaction solution was added with water, and extracted with ethyl acetate. The organic layer was washed with a saturated aqueous solution of ammonium chloride and a saturated aqueous solution of sodium hydrogen carbonate, dried with magnesium sulfate, and then distilled under reduced pressure to remove ethyl acetate, and then dried under vacuum, thereby to give 5.12 g of Compound 6.
