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, R1 is a lower alkyl group and the like, R2 is a lower alkyl group optionally having substituent(s) and the like, M is an alkali metal and X1 is a halogen atom.
化合物(II)在碱金属烷氧化物等存在下与甲酸酯反应,得到化合物(III);然后与化合物(IVa)或化合物(IVb)反应得到化合物(V);然后与化合物(VI)反应得到化合物(VII);最后去保护得到化合物(I)。本发明提供了一种工业上有利的生产方法,用作药物产品的合成中间体的4-乙酰嘧啶化合物:其中X是甲硫基团等,R1是较低的烷基团等,R2是具有取代基的较低的烷基团等,M是碱金属,X1是卤原子。
