Reaction Steps

To a solution of methyl 2,2-dimethyl-1,2,3,4-tetrahydroquinoline-8-carboxylate (0.138 g, 0.629 mmol) in THF (5 mL) and H2O (5 mL) was added a 1N aqueous solution of sodium hydroxide (1.88 mL, 1.88 mmol). After stirring at 50° C. overnight the reaction mixture was acidified to pH 2 using 1N aqueous HCl, extracted with ethyl acetate (three times), dried over MgSO4 and concentrated under vacuum to afford the desired compound that was used without further purification.
