Reaction Steps

The title compound was prepared following Protocol A. (S)-1-(4-Chloro-3-methoxyphenyl)-3-methylpiperazine dihydrochloride and [3-(1H-imidazol-2-yl)pyrazolo[3,4-b]pyridin-1-yl]acetic acid were used as the coupling components. The crude product was purified by silica gel chromatography (1% to 8% MeOH in CH2Cl2) to provide 1-[(S)-4-(4-chloro-3-methoxyphenyl)-2-methylpiperazin-1-yl]-2-[3-(1H-imidazol-2-yl)-pyrazolo[3,4-b]pyridin-1-yl]ethanone as a tan solid: 1H NMR (CDCl3, 400 MHz) δ 8.79 (dd, 0.6H), 8.66 (dd, 0.4H), 8.57-8.55 (m, 1H), 7.29-7.19 (m, 4H), 6.44-6.39 (m, 2H), 5.42 (br. s, 2H), 4.83 (br. s, 0.3H), 4.49 (br. s, 0.3H), 4.30 (br. s, 0.3H), 3.89 (s, 1.2H), 3.88 (s, 1.8H), 3.83 (br. s, 0.3H), 3.72-3.69 (m, 1H), 3.54-3.52 (m, 1H), 3.38 (br. s, 1H), 3.19-3.15 (m, 1H), 3.00 (br. s, 1H), 2.80 (br. s, 1H), 1.50-1.43 (m, 3H); LC/MS m/z (M+H)+ 466.4.
