    • The present invention relates to a method for producing a pyrimidine derivate useful as a neurocyte neurocyte necrosis inhibitor and an intermediate thereof. Disclosed is a method for producing an acid salt of 4-(4-fluorophenyl)-2-methyl-6-(5-piperidinopentyloxy) pyrimidine. The method comprises reacting 4-chloro-6-(4-fluorophenyl)-2-methylpyrimidine with 5-piperidino-1-pentanol, hydrating the thus obtained 4-(4-fluorophenyl)-2-mehtyl-6-(5-piperidinopentylox) pyrimidine and then converting the resultant the hydrate into an acid salt. The hydrate as a describe above; and a method for producing the hydrate is part of this invention. According to the present invention, a highly pure acid salt of 4-(4-fluorophenyl)-2-methyl-6-(5-piperidinopentyloxy) pyrimidine can be readily and efficiently produced without using a column chromatography. Thus, this method is suitable for the production thereof on a industrial scale.
    • 本发明涉及可用作神经细胞神经细胞坏死物抑制剂的嘧啶衍生物及其中间体的制备方法。 公开了4-(4-氟苯基)-2-甲基-6-(5-哌啶基戊氧基)嘧啶酸盐的制备方法。 该方法包括使4-氯-6-(4-氟苯基)-2-甲基嘧啶与5-哌啶子基-1-戊醇反应,将由此得到的4-(4-氟苯基)-2-甲基-6-(5-哌啶子戊酸 )嘧啶,然后将所得水合物转化为酸盐。 水合物如上所述; 水合物的制造方法是本发明的一部分。 根据本发明,可以容易且高效地制备4-(4-氟苯基)-2-甲基-6-(5-哌啶基戊氧基)嘧啶的高纯度酸盐,而不使用柱色谱法。 因此,该方法适合于以工业规模生产。
