description | The disclosure describes a method of preparing pyridazinone derivatives comprising contacting a compound of formula (I) or a salt thereof: (I) with a compound of formula (II) or a salt thereof: (II) to form a compound of formula (III) or a salt thereof: (III). A compound of formula (III) can then be converted to a compound of formula (IV):(IV), which can be used for preparing compounds for treating a liver disease or disorder, or a lipid disease or disorder.
L'invention concerne un procédé de préparation de dérivés de pyridazinone comprenant la mise en contact d'un composé de formule (I) ou d'un sel de celui-ci : (I) avec un composé de formule (II) ou un sel de celui-ci : (II) pour former un composé de formule (III) ou un sel de celui-ci : (III). Un composé de formule (III) peut ensuite être converti en un composé de formule (IV):(IV), qui peut être utilisé pour préparer des composés servant à traiter une maladie ou un trouble hépatique, ou bien une maladie ou un trouble lipidique. |
