Reaction Steps

To a solution of (6S)—N-benzyl-6-(4-hydroxybenzyl)-8-(naphthalen-1-ylmethyl)-4,7-dioxooctahydro-1H-pyrazino[1,2-a]pyrimidine-1-carboxamide 60 mg (0.106 mmol) in dry-THF (2 ml), palmitoyl chloride 97 μl (0.319 mmol) and then triethylamine 45 μl (0.319 mmol) were added and stirred at room temperature overnight. The reaction mixture was diluted with ethyl acetate (10 ml) and washed with water (10 ml), saturated sodium bicarbonate (10 ml), water (10 ml), and brine (10 ml). The organic layer was dried with sodium sulfate and filtered. The filtrate was concentrated in vacuo and the residue was purified by Büchi silica gel column chromatography (chloroform:methanol=99:1 to 98:2) to obtain title compound 57.7 mg (68%).
