Procedure
A suspension of the product from step 11a (1.0 g, 2.5 mmol), thioacetic acid (3.0 mL), and triethylamine (0.25 mL, 1.8 mmol) was stirred for 6 h at room temperature while slowly becoming a clear solution. The reaction was partitioned between ethyl acetate and water. The organic layer was washed with aqueous sodium bicarbonate (2×), brine, dried over magnesium sulfate, and concentrated to give the crude product. This was purified by FCC on silica gel eluting ethyl acetate:hexanes (gradient) to give 3-acetylsulfanyl-3-{3-[4-(2-methyl-quinolin-4-ylmethoxy)-phenyl]-4,5-dihydro-isoxazol-5-yl}-propionic acid methyl ester (0.74 g, 63%) as an oil. MS found: (M+H)+=479.
