Reaction Steps

To a solution of 5-methyl-3-pyridin-2-yl-isoxazole-4-carboxylic acid ethyl ester (4.1 g, 18 mmol) in THF (229 mL) at 0° C. was added lithium aluminum hydride (367 mg, 10 mmol). And the resulting mixture stirred for 1 h at room temperature. Water (1.9 mL) was added carefully followed by aqueous sodium hydroxide (15%, 1.9 mL) and water (0.54 mL). The resulting suspension was stirred for 15 min at ambient temperature and filtered over Hyflo®. Concentration and trituration with heptane afforded the title compound (2.88 g, 86%) as a light yellow solid. MS: m/e=191.3 [M+H]+.
