Reaction Steps

) NaOH 1N (1 ml) was added dropwise to a stirred solution of (S)-[4-[[[4,5-dihydro-3-(3-pyridinyl)-5-isoxazolyl]carbonyl]amino]phenyl]phenylmethyl acetate (0.001 mol) in methanol (20 ml) and THF (20 ml) and the reaction mixture was stirred for one hour at RT. The solvent was evaporated under reduced pressure. The white solid residue was taken up into methanol. The precipitate was filtered off, washed with methanol and diethyl ether, then dried, yielding 0.2 g (92%) of (S)-4,5-dihydro-N-[4-(hydroxyphenylmethyl)phenyl]-3-(3-pyridinyl)-5-isoxazolecarboxamide (compound 57).
