실험 절차
A solution of 3-(2-pyridyldithio)propionic acid hydrazide HCl (41.5 mg, 0.156 mmol) in anhydrous methanol (5 ml) was added to (8S,10S)-6,8,11-trihydroxy-8-(hydroxyacetyl)-1-methoxy-10-{[(1S,3R,4aS,9S,9aR,10aS)-9-methoxy-1-methyloctahydro-1H-pyrano[4′,3′:4,5][1,3]oxazolo[2,3-c][1,4]oxazin-3-yl]oxy}-7,8,9,10-tetrahydrotetracene-5,12-dione [PNU-159682, compound IIA, prepared as reported in WO 9802446] (50 mg, 0.078 mmol). The solution was stirred in the dark at room temperature for 20 hours. The course of the reaction was followed by reverse-phase HPLC-MS. After this period the solvent was evaporated and the residue was purified by flash column chromatography (MeOH:CH2Cl2=0.2:9.8) on silica gel (230-400 mesh), affording 18 mg (yield 27%) of 53. MS (ESI): 853 [M+H]+. Retention time=5.52 min (method 2).
