6-Hydroxy-2-methylquinoline → HCID 178422868, compound

Participants

Reaction Steps

6-hydroxy-2-methylquinoline was treated with cis-4-tert-butylcyclohexanol under Mitsunobu conditions, affording 6-((trans)-4-tert-butylcyclohexyloxy)-2-methylquinoline, which in turn was oxidized with tert-butyl hydrogen peroxide and selenium dioxide in dioxane, providing 6-((trans)-4-tert-butylcyclohexyloxy)-2-formylquinoline. This aldehyde was then treated with t-butyl 3-aminopropionate and sodium cyanoborohydride in dichloroethane to afford t-butyl 3-(((6-((trans)-4-tert-butylcyclohexyloxy)-quinolin-2-yl)methyl)amino)propionate. Treatment with lithium hydroxide in methanol/THF gave the title compound, 3-((6-((trans)-4-tert-butylcyclohexyloxy)quinolin-2-yl)methylamino)propanoic acid.
