Abstract
PURPOSE: To obtain the titled compound useful as an intermediate for a chemically modifying agent for antibiotics, by reacting a readily obtainable 4-hydroxyacetophenone with thallic nitrate at a temperature ≤30°C, followed by heating them ≥35°C and reaction.
CONSTITUTION: A 4-hydroxyacetophenone (e.g., 4-hydroxyacetophenone, 4-hydroxy-5-chloroacetophenone, etc.) shown by the formula (X is H or halogen) is reacted with thallic nitrate in an alcohol solvent preferably in the presence of a strong acid (e.g., perchloric acid, etc.) at ≤30°C, the substances are continuously heated to ≥35°C, and the reaction is continued, to give the desired substance shown by the formula II (R is lower alkyl).
EFFECT: The heating during the reaction provides the desired substance by a simple process.
