YieldReaction ConditionsOperation in experiment
With 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; In N,N-dimethyl-formamide; for 2h; '-TrifluoroacetyWjS-diPNZ-l^N-Boc-S-amino-ZCSJ-hydroxy-propionyl)- sisomicin To a stirring solution of N-Boc-S-amino-l^-hydroxy-propionic acid (1.30 g, 6.34 mmol) in DMF (14 ml) was slowly added HONB (1.14 g, 6.34 mmol) and EDC (1.21 g, 6.34 mmol) and the reaction mixture was stirred for 2 hours, when MS showed complete formation of the activated ester (MS m/e [M+Na]+ calcd 389.1, found 389.1). 6'-trifluoroacetyl-23-diPNZ-sisomicin (4.76 g, 5.28 mmol) was then added and the reaction was allowed to stir overnight. The reaction was quenched with sat. aq. NaHCO3 (10 ml) and was extracted with EtOAc (5 x 15 mL). The combined organic layers were dried over Na2SO4, filtered and evaporated to dryness to yield a crude, which was purified by RP HPLC Method 2-Column B to yield the desired 6'- trifluoroacetyl-2',3-diPNZ-l -(N-Boc-3-amino-2(5)-hydroxy-propionyl)-sisomicin (1.66 g, 1.52 mmol, 29% yield, >;95% purity): MS m/e [M+H]+ calcd 1089.4, found 1089.2, [M+Na]+ 1111.3.
