PROCESS FOR PRODUCING 1-ALKOXYCARBONYL NITROGENOUS SATURATED HETEROCYCLIC DERIVATIVE |
摘要 |
<p>A method for producing N-protected heterocyclic compounds such as 1-alkoxycarbonyl-3-aminopyrrolidines through position-selective reaction at the nitrogen atom that constitutes the hetero ring of a nitrogen-containing saturated heterocyclic compound having two nitrogen atoms such as 3-aminopyrrolidine. A dialkyl dicarbonate (ROCO-O-COOR) is reacted with a nitrogen-containing saturated heterocyclic compounds having two nitrogen atoms, at pH of from 9 to 14 to obtain a high-purity 1-alkoxycarbonyl nitrogen-containing saturated heterocyclic compound.</p> |
