Abstract

PURPOSE:To industrially and advantageously purify the titled compound useful as an amino group-protecting agent, by distilling crude ditertiary butyl dicarbonate in the presence of a petroleum based hydrocarbon, such as liquid paraffin, having the specific boiling point and melting point. CONSTITUTION:Crude ditertiary butyl dicarbonate is purified by distillation. In the process, a petroleum based hydrocarbon (especially liquid paraffin, preferably e.g. ISOVG10(R)) having >=250 deg.C boiling point and <=20 deg.C melting point in an amount of at least 0.01, especially about 0.03-7 times based on the ditertiary butyl dicarbonate fed to a distillation apparatus is present therein to carry out the distillation. According to this method, the readily available substance is used to industrially extremely advantageously afford the aimed compound in high purity and good recovery ratio by the simple method.
