Versuchsvorschrift
A mixture of 3-chloro-6-trifluoromethylpyridazine (1.6 g, 8.80 mmol) and ammonium hydroxide (9 mL) in THF (3 mL) was heated at 100° C. in a microwave reactor for 1 h. After this period, the reaction mixture was evaporated and the residue was extracted with dichloromethane. The combined extract was dried over with MgSO4, filtered, and evaporated under reduce pressure to afford 301a (1.3 g, 93%) as a white solid. MS-ESI: [M+H]+ 164.1
