Reaction Conditions

Reaction Steps

0.15 ml of acetic acid and 0.32 ml (1.6 mmol) of (1-ethoxycyclopropoxy)trimethylsilane are added, in a reactor, to 0.10 g (0.27 mmol) of 2-(4-fluorophenyl)-6-(piperazin-1-yl)-3-(pyridazin-4-yl)imidazo[1,2-b]pyridazine in 3 ml of methanol. 1.2 ml (1.2 mmol) of a molar solution of sodium cyanoborohydride in tetrahydrofuran are then added. After stirring for 15 minutes, the mixture is heated at 50° C. for 2 hours. After cooling, the product is extracted with dichloromethane, and the organic phase is filtered over a hydrophobic cartridge and then concentrated under reduced pressure. The residue is chromatographed on a silica gel column, to give 0.064 g of product. The latter is crystallized from diisopropyl ether, to give 0.053 g of light yellow crystals after drying.
