실험 절차

To a solution of 1-trifluoroacetamido-2,3-dihydro-4-methoxy-1H-indene (0.44 g) and 4,5-diphenyl-2-bromomethyloxazole (0.55 g) in DMF was added K2CO3 (0.30 g). After being stirred for 12 hours, the solution was extracted with ethyl acetate. The mixture was washed with brine, dried over MgSO4 and evaporated in vacuo. The residue was purified by chromatography on silica gel to afford 1-[N-trifluoroacetyl-N-[(4,5-diphenyloxazol-2-yl)methyl]amino]-2,3-dihydro-4-methoxy-1H-indene (0.30 g).
