실험 절차
Hydrazine (0.34 mL, 1.04 mmol) was added to a solution of 3-(4-chloro-1-methyl-1H-pyrazolo[3,4-b]pyridin-6-yl)-2-fluorobenzonitrile 15 (0.030 g, 0.1046 mmol) in n-butanol and the reaction mixture was heated at 90° C. for 1 hour. The solvent was removed and diluted with ethylacetate, washed with saturated bicarbonate solution followed by brine. Drying and concentration gave 16.
