Water → 2-(4-Fluorophenyl)-3-(2-methoxypyrid-4-yl)-6-(4-methylpiperazin-1-yl)imidazo[1,2-b]pyridazine

Participants

Reaction Steps

To a solution under argon of 0.10 g (0.25 mmol) of 2-(4-fluorophenyl)-3-(2-fluoropyrid-4-yl)-6-(4-methylpiperazin-1-yl)imidazo[1,2-b]pyridazine in N-methylpyrrolidone is added 0.65 mL (3.4 mmol) of sodium methoxide at 30% by weight in methanol. After stirring for 4 days at room temperature, the medium is poured into 200 mL of water and the product is extracted with ethyl acetate. The organic phase is dried over sodium sulfate and then concentrated under reduced pressure to give a pale yellow solid.
