Procedure

A solution of N,N-dimethyl-3-(5-(3-(morpholine-4-carbonyl)phenyl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazolo[3,4-b]pyridin-3-yl)benzamide in 5% of perchloric acid in acetic acid (1 mL) was stirred for 1 h at room temperature. Saturated sodium bicarbonate solution was then added to the solution slowly until pH 8 and the mixture was stirred for 24 hours at room temperature. Ethyl acetate was then used for extraction and the organic layers were combined, dried over sodium sulfate, filtered and concentrated to dryness. Mass triggered reverse phase HPLC purification afforded N,N-dimethyl-3-(5-(3-(morpholine-4-carbonyl)phenyl)-1H-pyrazolo[3,4-b]pyridin-3-yl)benzamide (7.4 mg, 18% yield over two steps) as light yellow solids. 1H NMR (500 MHz, CDCl3) δ 2.99 (s, 3H), 3.10 (s, 3H), 3.46 (br, 2H), 3.61 (br, 2H), 3.76 (br, 4H), 7.40 (d, J=7.0 Hz, 1H), 7.47 (d, J=8.0 Hz, 1H), 7.52 (m, 2H), 7.64 (d, J=7.5 Hz, 1H), 7.68 (s, 1H), 7.98 (m, 2H), 8.62 (s, 1H), 8.85 (br, 1H). MS: m/z 456.1 (M+H+).
