실험 절차

Using N-Boc-L-tHyp(Tosyloxy)-OMe (5g, 10.5 mmol), powdered KOH (1.75 g, 26.5 mmol) and 4-nitrophenol (3.66 g, 26.3 mmol) after 4 days at reflux, 2.52 g (65%) of the corresponding 4-nitrophenyl ether was obtained by column chromatography (silica ge, ethyl acetate/hexane mixtures) and crystallization of the appropriate fractions from ethyl acetate/hexane (1:1). An alternate method is to triturate the oily crude and pentane several times [hexane doesn't work] and then add a very, small amount of ethyl acetate to solidify the product. The filtered, solid product may than be crystallized as above. Elemental analysis for C17H22N2O7 (366.324 g/mmol): Calculated C, 55.74; H, 6.05; N, 7.65. Found C, 55.71; H, 6.05; N, 7.65.
