Hydrazine hydrate (1:1) → HCID 86757101, compound

Participants

Reaction Steps

To a solution in methanol (15 ml) of the mixture containing [1-[(3-tert-butyl-4-hydroxyphenyl)methyl)-2-(1,3-dioxo-1,3-dihydroisoindol-2-yl)ethyl]carbamic acid tert-butyl ester, hydrazine monohydrate (2 ml) was added and the resulting mixture was stirred at room temperature for 4 hours. After filtering, the filtrate was concentrated under reduced pressure and the resulting residue was subjected to silica gel column chromatography (eluting solvent consisting of chloroform, methanol and aqueous ammonia at a ratio of 10:1:0.1) to give [2-amino-1-[(3-tert-butyl-4-hydroxyphenyl)methyl]ethyl]carbamic acid tert-butyl ester in the amount of 1.55 g (69%).
