Diisopropylethylamine → 3-fluoro-5-morpholin-4-yl-N-[4-(2-morpholin-4-yl-ethylamino)-naphthalen-1-yl]-benzamide

Participants

Reaction Steps

N4-(2-morpholin-4-yl-ethyl)-naphthalene-1,4-diamine (190 mg, 701 μmol), 3-fluoro-5-morpholinyl benzoic acid (236 mg, 1.05 mmol), HBTU (531 mg, 1.4 mmol) and diisopropylethylamine (0.37 ml, 2.1 mmol) are stirred at room temperature in dimethylformamide (10 ml) for 12 hours. The mixture is poured into ethyl acetate (100 mL) and washed with water (100 ml). The organic layer is dried over anhydrous sodium sulfate and evaporated to dryness. The residue is purified by column chromatography on silica gel eluted with 5% methanol in ethyl acetate to give 3-fluoro-5-morpholin-4-yl-N-[4-(2-morpholin-4-yl-ethylamino)-naphthalen-1-yl]-benzamide (72 mg). 1H NMR 300 MHz (CDCl3) 7.7-8.0 (m, 3H), 7.4-7.6 (m, 3H), 7.3 (m, 1H), 7.05 (m, 1H), 6.7 (m, 1H), 6.6 (m, 1H), 5.35 (m, 1H), 3.65-4.0 (m, 8H), 3.2-3.4 (m, 6H), 2.8 (m, 2H), 2.4-2.55 (m, 4H).
