tert-Butyl carbazate Chemical Properties,Uses,Production

Chemical Properties

White to pale yellow lumps

Uses

Starting material for preparing BOC-azide, a reagent to introduce the BOC amino protection.

Synthesis Reference(s)

Journal of the American Chemical Society, 82, p. 2725, 1960 DOI: 10.1021/ja01496a018
Chemical and Pharmaceutical Bulletin, 18, p. 217, 1970 DOI: 10.1248/cpb.18.217

Purification Methods

Distil it in a Claisen flask with a water or oil bath at ca 80o. After a couple of drops have distilled, the carbazate is collected as an oil which solidifies to a snow white solid. It can be crystallised with 90% recovery from a 1:1 mixture of pet ether (b 30-60o) and pet ether (b 60-70o). [Carpino et al. Org Synth Coll Vol V 166 1973, Caprino et al.
