A Convenient Rearrangement of 1-Phenylpyrrole-2-carboxaldehydes into Their 3-Isomers
摘要:
1-Phenylpyrrole-2-carboxaldehydes are selectively and in high yield converted by treatment with trifluoromethanesulfonic acid (triflic acid) to 1-phenylpyrrole-3-carboxaldehydes.

Herein, we disclose the discovery and optimization of 2-piperidin-4-yl-acetamide derivatives as MCH-R1 antagonists. Structural investigation of piperidin-4-yl-amide and piperidin-4-yl-ureas identified 2-piperidin-4-yl-acetamide-based MCH-R1 antagonists with outstanding in vivo efficacy but flawed with high affinity towards the hERG potassium channel. While existing hERG SAR information was employed to discover

The discovery and optimization of piperidin-4-yl-urea derivatives as MCH-R1 antagonists is herein described. Previous work around the piperidin-4-yl-amides led to the discovery of potent MCH-R1 antagonists. However, high affinity towards the hERG potassium channel proved to be an issue. Different strategies to increase hERG selectivity were implemented and resulted in the identification of piperidin-4-yl-urea
