EXAMPLE 242 l-(5-(4-(2 -hydroxy ethyl)-lH-pyrazol-l-yl)-4-(isopropylamino)pyridin- -b]pyridine-5-carbonitrile In a 20 mL microwave vial, l-(5-iodo-4-(isopropylamino)pyridin-2-yl)-lH- pyrazolo[3,4-b]pyridine-5-carbonitrile (50 mg, 0.12 mmol), 2-(lH-pyrazol-4-yl)ethanol (13.9 mg, 0.12 mmol), potassium carbonate (51.3 mg, 0.37 mmol) and Nl,N2- dimethylethane-l,2-diamine (6.54 mg, 0.074 mmol) were mixed in 1,4-dioxane (1 mL) at room temperature with stirring. While bubbling in nitrogen, copper(I) iodide (4.71 mg, 0.025 mmol) was added and the mixture was capped and heated with stirring at 110 C for 5 hours. After cooling, the reaction mixture was filtered, and the filtrate was concentrated under high vacuum and the residue was dissolved in DMF for purification. The product was purified via preparative HPLC to afford l-(5-(4-(2-hydroxyethyl)-lH- pyrazol-l-yl)-4-(isopropylandno)pyridin-2-yl)-lH-pyrazolo[3,4-b]pyridine-5-carbonitrile (4.4 mg, 8% yield). NMR (500MHz, DMSO-de) delta 9.11-8.97 (m, 2H), 8.65 (br s, IH), 8.36 (br s, IH), 8.17 (s, IH), 7.77 (s, IH), 7.39 (br s, IH), 7.26 (d, J=7.3 Hz, IH), 4.76 (br s, IH), 3.84-3.74 (m, IH), 3.67-3.59 (m, 2H), 2.67 (t, J=6.9 Hz, 2H), 1.24 (d, J=6.2 Hz, 6H); LC\/MS: 389.0 (M+H); HPLC rt 1.37 min, conditions C.<\/p>\n

According to the analysis of related databases, 180207-57-2, the application of this compound in the production field has become more and more popular.<\/p>\n
