Reaction Steps

A thick walled glass tube was charged with N-{4-[8-chloro-2-(3-nitrophenyl)imidazo[1,2-α]pyridin-3-yl]-2-pyrimidinyl}-N-cyclopentylamine (44 mg, 0.10 mmol) and morpholine (4 mL). The vessel was sealed and heated to 150° C. for 4 days. The mixture was concentrated in vacuo and purified via flash chromatography on silica gel (2:1 to 1:1 hexanes:ethyl acetate) to provide N-cyclopentyl-4-[8-(4-morpholinyl)-2-(3-nitrophenyl)imidazo[1,2-α]pyridin-3-yl]-2-pyrimidinamine (3 mg, 6%) as a yellow solid. 1H NMR (CDCl3): δ 8.92 (m, 1H), 8.67 (s, 1H), 8.21 (d, 1H), 8.13 (m, 1H), 8.01 (d, 1H), 7.53 (t, 1H), 6.83 (t, 1H), 6.61 (d, 1H), 6.40 (d, 1H), 5.33 (m, 1H), 4.33 (m, 1H), 4.00 (m, 4H), 3.58 (m, 4H), 2.14–2.06 (m, 2H), 1.83–1.54 (m, 6H); MS m/z 486 (M+1).
