How is 2-Methyl-2-propanyl [(1S,2R)-2-aminocyclopentyl]carbamate (CAS: 445479-01-6) typically synthesized?

2-Methyl-2-propanyl [(1S,2R)-2-aminocyclopentyl]carbamate is typically synthesized through a multistep process involving the reaction of 2-methylpropan-2-ol and (1S,2R)-2-aminocyclopentanol. The reaction is catalyzed by a strong base like sodium hydride, followed by the addition of an amine group. The yield is around 85%, and the selectivity is high due to the stereochemistry of the starting materials.
