Reaction Steps

To a stirred solution of 3-(4-fluoro-2-methoxyphenyl)-4-(thiophen-3-yl)-1-tosyl-1H-pyrazolo[3,4-b]pyridine 27 (50 mg 0.102 mmol) in methanol (10 mL) and water (5 mL) was added potassium carbonate (0.204 mmol) and the RM was heated to 60° C. overnight. After completion of the SM the solvents was completely distilled off, diluted with water and extracted with chloroform twice. The organic layer was dried over sodium sulphate. The crude product was passed through 100-200 mesh silica gel eluting the pre compound at 28-30% ethyl acetate in hexane as eluent to get the pale yellow colored solid of compound 3-(4-fluoro-2-methoxyphenyl)-4-(thiophen-3-yl)-1H-pyrazolo[3,4-b]pyridine 28. 1H NMR (CDCl3) δ: 8.56(d,1H), 7.44(m,1H), 7.23(m,1H), 7.16(m,1H), 7.02(m,1H), 6.95(m,1H), 6.73(m,1H), 6.34(m,1H) and MS m/z=325.8.
