How is tert-butyl 3-amino-3-(hydroxymethyl)pyrrolidine-1-carboxylate (CAS: 889949-18-2) typically synthesized?

Tert-butyl 3-amino-3-(hydroxymethyl)pyrrolidine-1-carboxylate can be synthesized via a multistep process involving the protection of a pyrrolidine ring with tert-butyl, followed by the introduction of an amino group and a hydroxymethyl group. Commonly, this involves reagents such as tert-butyldiphenylsilyl chloride and hydrogenation catalysts like palladium on carbon. The synthetic route yields a highly pure product with good selectivity and high yield.
