PROCESS FOR PRODUCTION OF 4-ACETYLPYRIMIDINES AND CRYSTALS THEREOF |
摘要 |
Compound (II) is reacted with formate in the presence of an alkali metal alkoxide and the like to give compound (III); then this is reacted with compound (IVa) or compound (IVb) to give compound (V); then this is reacted with compound (VI) to give compound (VII); and then this is deprotected to give compound (I). The present invention provides an industrially advantageous production method of a 4-acetylpyrimidine compound useful as a synthetic intermediate for a pharmaceutical product:
wherein X is a methylthio group and the like, R 1 is a lower alkyl group and the like, R 2 is a lower alkyl group optionally having substituent(s) and the like, M is an alkali metal and X 1 is a halogen atom.
