Phthalimide → HCID 89666941, compound

Participants

Reaction Steps

Phthalimide (0.147 g), triphenylphosphine (0.34 g), and diisopropyl azodicarboxylate (0.684 ml) were added to a THF (5 ml) solution containing tert-butyl ((2S)-1-(2,2-dimethylcyclopropyl)-1-hydroxypropan-2-yl)carbamate (0.20 g), followed by stirring at room temperature for 1.5 hours. The solvent was distilled away under reduced pressure and the obtained residue was purified by silica gel chromatography (n-hexane:ethyl acetate=1:0 to 1:0.2). A yellow liquid of tert-butyl ((2S)-1-(2,2-dimethylcyclopropyl)-1-(1,3-dioxoisoindolin-2-yl)propan-2-yl)carbamate (22.4 mg) was thus obtained.
