How is tert-Butyl (3-hydroxypropyl)(isopropyl)carbamate (CAS: 873437-13-9) typically synthesized?

t-Butyl (3-hydroxypropyl)(isopropyl)carbamate (CAS: 873437-13-9) can be synthesized via a multi-step reaction involving the formation of an intermediate amide, followed by alkylation of the hydroxy group. The synthesis typically uses tert-butanol, 3-hydroxypropyl isopropylamine, and a suitable base like triethylamine as a catalyst. The process yields a high purity product with good selectivity and high yield, making it suitable for industrial applications.
