N-[4-(4-Fluorophenyl)-5-(hydroxymethyl)-6-isopropylpyrimidin-2-yl]-N-methylmethane sulfonamide (I), an important intermediate to synthesize rosuvastatin, an HMG-CoA reductase inhibitor. It was prepared from methyl 4-(4-fluorophenyl)-6-isopropyl-2-(methylamino)pyrimidine-5-carboxylate (1) via mesylation by mesyl chloride and sodium tert-pentoxide, then reduction by DIBAL/HCl. The product was characterized by NMR and LC-MS. The crystal structure of compound I was investigated using X-ray diffraction and SHELXTL-97 software. The result indicated that compound I crystallized in the monoclinic system, space group C2/C with a = 29.683(6), b = 7.6290 (15), c = 18.215(4) Å, V = 3451.1 (16) Å3; Z 8.
N-[4-(4-氟苯基)-5-(羟甲基)-6-异丙基嘧啶-2-基]-N-甲基甲磺酰胺(I),是合成HMG-CoA还原酶抑制剂瑞舒伐他汀的重要中间体。由4-(4-氟苯基)-6-异丙基-2-(甲氨基)嘧啶-5-甲酸甲酯(1)经甲磺酰氯和叔戊醇钠甲磺化,然后用DIBAL/HCl还原制备。通过NMR和LC-MS对产物进行了表征。使用X射线衍射和SHELXTL-97软件研究了化合物I的晶体结构。结果表明,化合物I为单斜晶系结晶,空间群C2/C,a=29.683(6),b=7.6290(15),c=18.215(4)Å,V=3451.1(16)Å3; Z 8.
