CIS-3-AMINOCYCLOBUTANECARBOXYLIC ACID can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly used in laboratory research and development process and chemical production process.

 
Azide 10a (0.30 g, 1.9 mmol) was dissolved in methanol (5 mL); then 6N HCl (2 mL) and 10% palladium on charcoal were added to the solution. The resulting mixture was stirred under 1 bar of hydrogen for 3 h, then the catalyst was filtered off, and the solvent was removed under reduced pressure. The residue was dissolvedin 6N HCl (5 mL) and refluxed upon stirring for 1 h, then evaporated in vacuum. The residue was purified by ion-exchange chromatography (Amberlite? IR-120(plus) ion-exchange resin, 3.5% aqueous ammonia as an eluent). cis-3-aminocyclobutanecarboxylic acid 1a as white powder, yield 0.16 g, 1.4 mmol, 71%.
