PROCEDURE
实验过程
Diisopropyl azodicarboxylate (0.3 mL, 1.5 mmole) was added to a solution of (S)-8-hydroxy-3-oxo-2-(2-phenylethyl)-2,3,4,5-tetrahydro-1H-2-benzazepine-4-acetate (350 mg, 1.0 mmole), 6-(methylamino)-2-pyridylethanol (228 mg, 1.5 mmole), and triphenylphosphine (393 mg, 1.5 mmole) in anhydrous THF (10 mL) at 0° C. The mixture was allowed to warm to RT over 72 hr then was concentrated. Flash silica gel chromatography (50% EtOAc/hexanes) followed by a second flash silica gel chromatography (25% EtOAc/hexanes) gave the title compound as a white foam (250 mg, 51%): MS (ES) m/e 488 (M+H)+.
