실험 절차

Following a procedure analogous to that used in Example step 1c, but using 3,3-dimethyl-pent-4-enoic acid methyl ester and 4-(2-methyl-quinolin-4-ylmethoxy)-benzaldehyde oxime from step 1b, the crude reaction was partitioned between ethyl acetate and water and the organic layer was washed with brine, dried over magnesium sulfate, and concentrated to give 3-methyl-3-{3-[4-(2-methyl-quinolin-4-ylmethoxy)-phenyl]-4,5-dihydro-isoxazol-5-yl}-butyric acid methyl ester (0.14 g, 100%) as a crude oil. MS found: (M+H)+=433.
