Versuchsvorschrift

Sodium methoxide (28% in methanol) (0.050 mL, 0.22 mmol) was added to a suspension of the product from step 11b (0.085 g, 0.18 mmol) in methanol (1.5 mL) at room temperature. The reaction turned clear and was stirred for 45 minutes, and then methyl iodide (0.05 mL, 0.80 mmol) was added. The reaction was stirred an additional 45 minutes, quenched with aqueous ammonium chloride, concentrated to remove the methanol, and partitioned between ethyl acetate and water. The organic layer was washed with brine, dried with magnesium sulfate, and concentrated to give 3-{3-[4-(2-methyl-quinolin-4-ylmethoxy)-phenyl]-4,5-dihydro-isoxazol-5-yl}-3-methylsulfanyl-propionic acid methyl ester (0.08 g, 99%) as an oil. MS found: (M+H)+=451.
