Reaction Steps

) A mixture of compound (56) (0.001 mol) in methanol (100 ml) was cooled to 0° C. NaOH 1N (0.0288 mol) was added and the reaction mixture was stirred overnight at RT. The reaction mixture was re-cooled to 0° C. 1 N HCl (30 ml) was added and this mixture was extracted with CH2Cl2. The separated organic layer was dried (MgSO4), filtered and the solvent evaporated under reduced pressure. The residue was crystallized from ethanol. The precipitate was filtered off, washed with ethanol, and dried, yielding 0.2 g (5.2%) (±)-4-[[[4,5-dihydro-3-(3-pyridinyl)-5-isoxazolyl]carbonyl]amino]-α-phenylbenzeneacetic acid (compound 406).
