4-(Trifluoromethyl)benzaldehyde → HCID 59253662, compound

Participants

Reaction Steps

To a mixture of 6-(piperidin-4-ylamino)-pyridazine-3-carbonitrile (D3) (0.15 g, 0.7 mmol) and α,α,α-trifluoro-p-tolualdehyde (0.15 ml, 1.1 mmol) in dichloromethane (2 ml), was added sodium triacetoxyborohydride (0.232 g, 1.1 mmol) and acetic acid (0.041 ml). The reaction mixture was then stirred at room temperature for 18 h. A saturated solution of sodium hydrogen carbonate was then added and the organic layer was separated, dried (Na2SO4), filtered and the solvent evaporated in vacuo. The residue was purified by HPLC. The desired fractions were collected and the solvent was evaporated in vacuo to yield E7 (0.101 g, 38%) as a solid. C18H18F3N5 requires 361. Found 362 (MH+); mp: 243.1° C.
