Reaction Steps

To a solution of 1-[1-(4,5-diphenyloxazol-2-yl)ethylamino]-1,2,3,4-tetrahydro-5-methoxynaphthalene (0.33 g) in CH2Cl2 (7 ml) was added 1M BBr3 -CH2Cl2 solution (1.5 ml) at 0° C. After being stirred for 3 hours at the same temperature, the solvent was evaporated in vacuo. The residue was partitioned between ethyl acetate and sat. NaHCO3. The organic layer was washed with water and 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-hydroxynaphthalene (0.23 g). MS (m/z): 411 (M+ +1) NMR (CDCl3, δ): 1.57 (3H, d, J=6.8 Hz), 1.64-2.20 (4H, m), 2.44-2.86 (2H, m), 3.89 (0.5H, m), 4.12 (0.5H, q, J=6.8 Hz), 4.29 (0.5H, q, J=6.8 Hz), 4.78 (0.5H, m), 6.62-6.72 (1H, m), 6.97-7.14 (2H, m), 7.32-7.41 (6H, m), 7.58-7.68 (4H, m)
