A series of 1-(1-indolinyl)-2-propylamines was synthesised and evaluated as 5-HT2C receptor agonists for the treatment of obesity. The general methods of synthesis of the precursor indoles are described. The functional efficacy and radioligand binding data for all of the compounds at 5-HT2 receptor subtypes are reported. A number of compounds were found to reduce food intake in rats after oral administration. (C) 2004 Published by Elsevier Ltd.
Use of a Modified Leimgruber–Batcho Reaction to Prepare 6‐Chloro‐5‐fluoroindole
摘要:
An efficient synthesis of the title indole, the heterocyclic core of the standard 5-HT2C receptor agonist Ro 60-0175, via a modified Leimgruber-Batcho indole synthesis is presented. The process can be used to make > 100 g quantities of the target indole.
