Versuchsvorschrift
A mixture of 5-chloro-2-fluoro-benzaldehyde (109) (5 g, 31.6 mmol) and guanidine carbonate (7.5 g, 41.1 mmol) was heated at 140° C. in DMA (50 mL) for 3 h. 100 ml water was added and after refrigeration, a solid was isolated by filtration, and dried under vacuum to give the product (110) (2.8 g, 15.8 mmol, 50% yield). ESI-MS (M+1): 180 calc. for C8H6ClN3 179.
Aufarbeitung
- customafter refrigeration, a solid was isolated by filtration
