Reaction Steps

To a solution of 4,4-dimethyl-2-oxo-1,2,3,4-tetrahydro-1-isopropyl-7-[(trimethylsilyl)ethynyl]quinoline (Compound 29) in 7.0 ml of methanol was added potassium carbonate. The mixture was stirred at room temperature for 10 h. The reaction mixture was then concentrated in vacuo and the resulting oil was dissolved in water, and extracted using methylene chloride (2×). The organic layers were dried (MgSO4), filtered and concentrated in vacuo to give the title compound as an oil.
