実験手順
To a solution of N-(1-benzyl-1H-indazol-4-yl)-7-vinylimidazo[1,2-a]pyridine-3-carboxamide (27 mg; 0.069 mmol) in acetone/water (3:2; 1 mL) were added osmium tetroxide (0.1 equivalents as a 2% solution in t-butanol) and N-methylmorpholine N-oxide (1.2 equivalents as a 50% solution on water). The mixture was stirred at ambient temperature for several days. Further aliquots of osmium tetroxide and N-methyl morpholine N-oxide were added at intervals until the reaction was complete by LC. The mixture added to water and extracted into ethyl acetate. Some insoluble material was isolated by filtration. The extracts were combined, concentrated under vacuum and combined with the solids isolated by filtration. The combined material was purified by preparative thin layer chromatography on silica, eluting with dichloromethane/ethanol/ammonium hydroxide (100:20:0.5) to give the desired product (2.6 mg). MS (APCI), m/z=428.2 (M+H).
