Reaction Steps
A solution of NaH (60% oil, 66 mg) and 1-[1-(4,5-diphenyloxazol-2-yl)ethylamino]-1,2,3,4-tetrahydro-5-hydroxynaphthalene (0.55 g) in DMF (10 ml) was stirred for 30 minutes at room temperature. To the reaction mixture was added ethyl bromoacetate (0.26 g). After being stirred for 7 hours at room temperature, the solution was partitioned between ethyl acetate and sat. NaHCO3. The organic layer was washed with brine. The dried solvent was evaporated in vacuo. The residue was purified by chromatography on silica gel to give 1-[1-(4,5-diphenyloxazol-2-yl)ethylamino]-1,2,3,4-tetrahydro-5-ethoxycarbonylmethoxynaphthalene (0.38 g).
