Procedure

A solution of 1-[1-(4,5-diphenyloxazol-2-yl)ethylamino]-1,2,3,4-tetrahydro-5-ethoxycarbonylmethoxynaphthalene (0.24 g), iodomethane (77 mg) and K2CO3 (82 mg) in DMF (5 ml) was stirred for 5 hours at room temperature. The reaction mixture was partitioned between ethyl acetate and water. 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-[N-methyl-N-[1-(4,5-diphenyloxazol-2-yl)ethyl]amino]-1,2,3,4-tetrahydro-5-ethoxycarbonylmethoxynaphthalene (0.12 g). MS (m/z): 511 (M+ +1) IR (Film): 1730 cm-1NMR (CDCl3, δ): 1.29 (3H, t, J=7.1 Hz), 1.63 (3H, d, J=7.1 Hz), 1.58-1.88 (3H, m), 1.95-2.18 (1H, m), 2.26 (3H, m), 2.46-2.68 (1H, m), 2.80-3.00 (1H, m), 4.12 (2H, q, J=7.1 Hz), 4.26 (3H, q, J=7.1 Hz), 4.60 (2H, s), 6.56 (1H, d, J=7.9 Hz), 7.11 (1H, dd, J=7.9, 7.9 Hz), 7.26-7.50 (7H, m), 7.59-7.68 (4H, m)
