Reaction Steps

A mixture of 3,5-diisopropylsalicylic acid (Intermediate 9, 25 g, 0.11 mol, available from Aldrich) and quinoline (50 mL) was refluxed for 4 h. The mixture was cooled to room temperature, diluted with EtOAc (200 mL), washed with 1M HCl (2×200 mL) until acidic, then with brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (5% then 10% EtOAc-hexanes) to yield the title compound as a yellow oil (20 g, ˜100%).
