Reaction Steps

A solution of Clorox® was added dropwise (1 mL) to a solution of vinyl acetic acid (0.071 g, 0.8 mmol) and 4-(2-methyl-quinolin-4-ylmethoxy)-benzaldehyde oxime (0.12 g, 0.40 mmol) in THF (4 mL) under nitrogen atmosphere at room temperature. The reaction was stirred overnight, partitioned between ethyl acetate and water saturated KH2PO4 solution. The organic layer was washed with brine, dried over magnesium sulfate and concentrated to give {3-[4-(2-methyl-quinolin-4-ylmethoxy)-phenyl]-4,5-dihydro-isoxazol-5-yl}-acetic acid (0.15 g, 100%) as a crude solid. MS found: (M+H)+=377.
