  描述：

  N-[3-(piperidin-4-yl)phenyl]-acetamide 、 4-(4-chlorophenyl)-2-(3-chloropropyl)-4,5-dimethylpyridazine-3(2H)-one 在 sodium carbonate 、 sodium iodide 作用下， 以 N,N-二甲基甲酰胺 为溶剂， 反应 2.0h， 以29%的产率得到2-[3-[4-[(3-acetylamino)phenyl]piperidin-1-yl]propyl]-6-(4-chlorophenyl)-4,5-dimethylpyridazin-3(2H)-one

  名称：

  4-Arylphthalazin-1(2H)-one derivatives as potent antagonists of the melanin concentrating hormone receptor 1 (MCH-R1)

  摘要：

  A novel series of 4-arylphthalazin-1(2H)-one linked to arylpiperidines were synthesized and evaluated as MCH-R1 antagonists. The results of an extensive SAR study probing the effects of substituents on the 4-arylphthalazin-1(2H)-one C-4 aryl group led to the identification of the 4-(3,4-difluorophenyl) derivative as a highly potent MCH-R1 inhibitor with an IC50 = 1 nM. However, further investigations showed that this substance has unacceptable pharmacokinetic properties including a high clearance and volume of distribution. (C) 2011 Elsevier Ltd.
