PROBLEM TO BE SOLVED: To provide a method for simply and industrially producing 3-formyl-2,2,5,5-tetramethylpyrrolin-1-oxyl. SOLUTION: The method for producing the 3-formyl-2,2,5,5-tetramethylpyrrolin-1-oxyl is characterized by reacting 3-carboxy-2,2,5,5-tetramethylpyrrolin-1-oxyl with a 1 to 6C alcohol and then reacting the obtained 3-alkyl ester-2,2,5,5-tetramethylpyrrolin-1-oxyl with a reducing agent. The 3-formyl-2,2,5,5-tetramethylpyrrolin-1-oxyl can thereby simply and industrially be produced. COPYRIGHT: (C)2011,JPO&INPIT |
