Tetrahydrofuran → 4-[(3-Isopropylphenyl)amino]-6-(2-morpholin-4-ylethoxy)-1,7-naphthyridine-3-carbonitrile

Participants

Reaction Steps

To 6-fluoro-4-[(3-isopropylphenyl)amino]-1,7-naphthyridine-3-carbonitrile (0.050 g, 0.16 mmol) was added a 1 M solution of freshly prepared alkoxide of N-(2-hydroxyethyl)morpholine in THF (1.88 mL, 1.88 mmol). The reaction was heated to reflux for 2 hours. The solvent was evaporated and water was added. Diethyl ehter and methylene chloride was added and crystals formed. The product was collected by filtration to give a yellow solid (0.044 g, 66%). 1H NMR (400 MHz, DMSO-D6) δ ppm 1.2 (d, J=6.8 Hz, 6 H) 2.5 (m, 2 H) 2.7 (t, J=5.8 Hz, 2 H) 2.9 (m, 1 H) 3.3 (m, 2 H) 3.6 (m, 4 H) 4.5 (t, J=5.8 Hz, 2 H) 7.1 (m, 3 H) 7.3 (t, J=8.7 Hz, 1 H) 7.8 (s, 1 H) 8.4 (s, 1 H) 9.0 (s, 1 H) 9.9 (s, 1 H).
