Reaction Steps
) Methanesulfonyl chloride (0.010 mol) was added to a solution of compound (51) (0.005 mol) and triethylamine (0.013 mol) in CH2Cl2 (100 ml, dried over MgSO4), stirred at 0° C. The resulting reaction mixture was stirred for 1 hour at 10° C. Water was added. The organic layer was separated, dried (MgSO4), filtered and the solvent was evaporated under reduced pressure. The residue was purified by short column chromatography over silica gel (eluent: CH2Cl2/CH3OH 97/3). The pure fractions were collected and the solvent was evaporated under reduced pressure. The residue was crystallized from EtOAc. The precipitate was filtered off, washed with EtOAc, then dried, yielding 0.5 g (27%) of (±)-4,5-dihydro-N-[4-(1-phenylethenyl)phenyl]-3-(3-pyridinyl)-5-isoxazolecarboxamide (compound 378).
