Reaction Steps

Potassium superoxide (0.50 g) was added to a solution of 1-(5-bromopentanoyl)-1,2,3,4-tetrahydroquinoline (1.8 g) and 18-Crown-6 (0.4 g) in dimethylsulfoxide (25 ml). After 8 hours the solution was added to water and extracted with ether. The extract was washed, dried and evaporated and the residue was chromatographed on silica gel, eluting with 95:5 methylene chloride:methanol, to yield 1-(5-hydroxypentanoyl)-1,2,3,4-tetrahydroquinoline.
