Method for producing halogenated β-lactam compound |
| abstract |
(57) [Problem] An industrially valuable, inexpensive and safe halogenation using water as a reaction solvent without using an organic solvent having many problems from the viewpoint of safety and environmental pollution. β -To provide a method for efficiently producing a lactam compound in high yield. SOLUTION: A β-lactam amino compound represented by the general formula (1) is reacted with nitrite or nitrite in water in a slurry dispersion state in water in the presence of a halogen molecule under acidic conditions to obtain a compound of the general formula (4) A method for producing a halogenated β-lactam compound, characterized by obtaining a halogenated β-lactam compound represented by the formula: Embedded image [N shows the integer of 0-2. A represents the formula (2) or (3). [Chemical formula 2] [A is the same as above. X 1 represents a hydrogen atom or a halogen atom. X 2 represents a halogen atom. ] |
