Reaction Steps

To 150 ml of tetrahydrofurane of 14.50 of D-leucic acid, 15.2 g of triethylamine and then 14.4 ml of benzyl bromide are added, and the solution was stirred for 3 hours while refluxing. The insoluble matter produced from the reaction solution was filtered off, and the filtrate was concentrated in vacuo. The obtained residue was dissolved and extracted in 150 ml of ethyl acetate. The ethyl acetate layer was washed twice with saturated bicarbonate water, twice with 1N hydrochloric acid, and twice with saturated brine sequentially, and dried over sodium sulfate anhydride, and concentrated in vacuo. The obtained oily residue was dried, and the captioned compound was obtained. Yield: 18.34 g.
