titleOfInvention | PROCESS TO PREPARE A SUBSTITUTED AND CRYSTAL POLYCHYCLIC PIRIDONA DERIVATIVE |
abstract | The present application provides a process for preparing a compound of formula (2), where R² is unsubstituted alkyl, characterized in that the reaction of a compound of formula (1), where R¹ is hydrogen or a protecting group other than alkyl does not substituted, with a compound of the formula: R²-OH, where R² is as defined above, in the presence of a sodium salt and/or a magnesium salt, and compounds. Claim 6: A process for preparing a compound of formula (4), wherein R³, R⁴, R⁵ and R⁶ are each independently hydrogen or halogen, with the proviso that one or two of R³, R⁴, R⁵ and R⁶ it is halogen; characterized in that the reaction of a compound of the formula (2'), with a compound of the formula (3), where R³, R⁴, R⁵ and R⁶ are as defined above. Claim 8: A process for preparing the compound of formula (5) or formula (6), characterized in that it comprises the process according to any of claims 1 to 7. Claim 9: A compound of formula (2') or a salt of this Claim 12: A compound of formula (4') or a salt thereof. Claim 15: A crystal of the compound of the formula (5), or a crystal of a pharmaceutically acceptable salt thereof. |
