How is 2-Methyl-2-propanyl 3-[methoxy(methyl)carbamoyl]-1-piperidinecarboxylate (CAS: 189442-78-2) typically synthesized?

2-Methyl-2-propanyl 3-[methoxy(methyl)carbamoyl]-1-piperidinecarboxylate is typically synthesized using a multistep process involving the formation of a piperidine ring followed by carbamoylation. Commonly, this involves the reaction of an appropriate precursor with methoxy(methyl) isocyanate under basic conditions. The reaction is selective and yields up to 90% purity.
