실험 절차

To a solution of 3-tert-butoxy-benzoic acid (0.15 g, 0.774 mmol) in dimethylformamide (5 ml) is added HBTU (0.44 g, 1.5 eq) followed by the addition of diisopropylethylamine (0.296 ml, 3.0 eq). The mixture is stirred at room temperature for five minutes. A solution of 4-(2-morpholin-4-yl-ethoxy)-naphthalen-1-ylamine (0.21 g) in dimethylformamide (2 ml) is then added. This mixture is stirred at room temperature for 15 h, diluted with water and extracted with ethyl acetate. The organic layer is washed with water, dried over Na2SO4 and evaporated. The residue is purified by column chromatography on silica gel (ethyl acetate) to give 3-tert-butoxy-N-[4-(2-morpholin-4-yl-ethoxy)-naphthalen-1-yl]-benzamide (0.146 g). Mp: 50-51° C. 1H NMR (300 MHz, DMSO-d6) δ 10.25 (s, 1H), 8.22 (m, 1H), 7.85 (m, 2H), 7.66 (s, 1H), 7.55 (m, 2H), 7.23 (d, J=7.5 Hz, 1H), 7.03 (d, J=8.1 Hz, 1H), 4.31 (t, J=5.1 Hz, 2H), 3.61 (t, J=4.2 Hz, 4H), 2.89 (brs, 2H), 2.58 (brs, 4H), 1.35 (s, 9H). MS: 449 (M+1).
