  描述：

  Tert-butyl 4-(5-bromo-6-chloropyridazin-4-yl)piperidine-1-carboxylate 在 palladium on activated charcoal 氢气 、 碳酸氢钠 作用下， 以 乙酸乙酯 为溶剂， 生成 Tert-butyl 4-(pyridazin-4-yl)piperidine-1-carboxylate

  名称：

  Potent heteroarylpiperidine and carboxyphenylpiperidine 1-alkyl-cyclopentane carboxamide CCR2 antagonists

  摘要：

  This report describes replacement of the 4-(4-fluorophenyl)piperidine moiety in our CCR2 antagonists with 4-heteroaryl piperidine and 4-(carboxyphenyl)-piperidine subunits. Some of the resulting analogs retained potency in our CCR2 binding assay and had improved selectivity versus the I-Kr channel; poor selectivity against I-Kr had been a liability of earlier analogs in this series.
