Participants

Reaction Steps

Using the general method of Example 47, furoyl chloride (15.8 μL, 0.16 mmol) was reacted with 4-(4-amino-2-butyl-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl)butaneamine (0.05 g, 0.16 mmole) to provide 0.019 g of N-[4-(4-amino-2-butyl-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl)butyl]-2-furamide as a white solid. 1H NMR (300 MHz, CDCl3) δ 8.58 (dd, J=4.4, 1.5 Hz, 1 H), 8.06 (dd, J=8.6, 1.6 Hz, 1 H), 7.41 (dd, J=8.5, 4.4 Hz, 1 H), 7.33 (m, 1 H), 7.08 (dd, J=3.5, 0.6 Hz, 1 H), 6.84 (m, 1 H), 6.47 (dd, J=3.5, 1.7 Hz, 1 H), 4.86 (apparent t, J=7.7 Hz, 2 H), 3.59 (apparent q, J=6.5 Hz, 2 H), 2.92 (apparent t, J=7.8 Hz, 2 H), 1.7-2.1 (m, 6 H), 1.51 (m, 2 H); 1.00 (t, J=7.3 Hz, 3 H); HRMS (EI) calcd for C22H26N6O2 (M+) 406.2117, found 406.2121.
