PROCESS FOR PRODUCING 1,4-BENZODIOXANE DERIVATIVES

摘要

PURPOSE: A manufacturing method for 1,4-benzodioxane derivative is provided to manufacture a carbonate compound by reacting a diol compound with a carbonate agent and to eliminate a protecting group for heating. CONSTITUTION: An industrial process for producing 1,4-benzodioxane derivatives (1), characterized by converting a diol (2) into a carbonate (3) with a carbonating agent, removing the protecting group, and cyclizing the obtained compound by heating or by treating with a base or fluoride salt.
