Reaction Steps

A mixture of 4-[7-chloro-2-(4-methoxyphenyl)pyrazolo[1,5-a]pyridin-3-yl]-N-cyclopropyl-2-pyrimidinamine (75 mg, 0.19 mmol) and 2-methoxyethylamine (5 mL, 58 mmol) was heated in a sealed tube at 140° C. for 24 hours. After cooling to room temperature, the mixture was concentrated. Flash chromatography (1:1 to 1:3 hexanes-ethyl acetate) provided 3-[2-(cyclopropylamino)-4-pyrimidinyl]-N-(2-methoxyethyl)-2-(4-methoxyphenyl)pyrazolo[1,5-a]pyridin-7-amine (77.7 mg, 95%) as a yellow solid. 1H NMR (CDCl3): δ 8.03 (d, 1 H), 7.96 (d, 1 H), 7.60 (d, 2 H), 7.31 (t, 1 H), 7.00 (d, 2 H), 6.41 (d, 1 H), 6.31 (t, 1 H), 6.04 (d, 1 H), 5.40 (broad, 1 H), 3.89 (s, 3 H), 3.72 (t, 2 H), 3.57 (q, 2 H), 3.43 (s, 3 H), 2.88 (m, 1 H), 0.88 (m, 2 H), 0.64 (m, 2 H); MS m/z 431 (M+1).
