Reaction Steps
The solution of (S)-2-tert-butoxy-2-(5-(4-chlorophenyl)-7-methyl-2-(trifluoromethylsulfonyloxy)quinolin-6-yl)ethyl pivalate (compound of Example 26) (35 mg, 0.06 mmol), ethynylbenzene (8 μL, 0.08 mmol), and triethylamine (1 mL) in ethyl acetate (0.5 mL) was degassed with nitrogen. Copper(I) iodide (1 mg) and bis(triphenylphosphine)palladium (II) dichloride (7 mg) were added, and the mixture was stirred for 12 hours. The mixture was diluted with ethyl acetate, washed with water and brine, and dried with sodium sulfate. Concentration and purification by flash column chromatography (silica gel, ethyl acetate/hexanes) gave (S)-2-tert-butoxy-2-(5-(4-chlorophenyl)-7-methyl-2-(phenylethynyl)quinolin-6-yl)ethyl pivalate. LCMS-ESI+ (m/z): [M+H]+ calcd for C35H37ClNO3: 554.2. Found: 554.3.
