Participants

Reaction Conditions

Reaction Steps

A mixture of 3-chloro-6-trifluoromethyl-pyridazine (1.6 g, 8.8 mmol) (prepared by a procedure similar to that described in Tetrahedron, 1999, 55 (52), 15067-15070) and ammonium hydroxide (30 ml) in THF (10 ml) was heated at 100° C. in a microwave reactor (Emrys Optimizer; 0-9 Barr) for 1 h. After this period, the reaction mixture was evaporated and the residue extracted with dichloromethane. The combined extracts were dried (MgSO4), filtered and the solvents evaporated in vacuo to give D6 (1.3 g, 93%). C5H4F3N3 requires 163; Found 164 (MH+)
