Participants

Reaction Steps

A solution of 3-[(tert-butoxycarbonyl)amino]-1-propanol (0.14 g, 0.8 mmol) and diethyl azodicarboxylate (0.13 mL, 0.8 mmole) in anhydrous DMF (2 mL) was added dropwise to a solution of methyl (±)-8-hydroxy-3-oxo-2,3,4,5-tetrahydro-1H-2-benzazepine-4-acetate (0.10 g, 0.4 mmole) and triphenylphosphine (0.21 g, 0.8 mmol) in anhydrous DMF (1.4 mL) and dry THF (2 mL) at RT under argon. The resulting solution was stirred for 18 hr, then was concentrated under vacuum. Silica gel chromatography (1%-3% MeOH/CH2Cl2) gave the title compound (0.11 g): MS (ES) m/e 407.3 (M+H)+.
