How is 2-Methyl-2-proanyl {(2S)-1-[(benzyloxy)amino]-3-hydroxy-3-methyl-1-oxo-2-butanyl}carbamate (CAS: 102507-19-7) typically synthesized?

2-Methyl-2-proanyl {(2S)-1-[(benzyloxy)amino]-3-hydroxy-3-methyl-1-oxo-2-butanyl}carbamate is typically synthesized via a multistep process involving the condensation of a benzylamine with a 2-methyl-2-propanol derivative. The synthesis often requires the use of a strong base, such as sodium hydride, and is carried out in an anhydrous solvent like tetrahydrofuran (THF). The overall yield is moderate to good, depending on the purity of the starting materials and the reaction conditions.
