YieldReaction ConditionsOperation in experiment
91% Example 165 Step D: 2- (2, 3-DIFLUOROPHENYL)-L- (LH-PYRAZOLO [3, 4-B] PYRIDIN-3-Y 1)ethanone [0442] To a solution of <strong>[145689-41-4]2,3-difluorophenylacetic acid</strong> (236mg, 1.4 mmol) in THF at OC was added 3.85 mL (3.85 mmol) of a solution of lithium bis-trimethylsilylamide in THF. The resulting solution was then added to solution of a 2: 1 mixture of ethyl lH-pyrazolo [3, 4-B] PYRIDINE-3-CARBOXYLATE and isopropyl LH-PYRAZOLO [3, 4-B] PYRIDINE-3-CARBOXYLATE (104mg, 0.55 mmol) in THF. The resulting mixture was heated at 75C for 3 hours. The reaction progress was monitored by TLC and HPLC and quenched with saturated NH4C1, diluted with EtOAc and washed with saturated NaHC03 and brine. The organic layer was dried over MgS04 and concentrated to give 137 mg (91% yield) of 2-(2, 3-DIFLUOROPHENYL)-1-(LH-PYRAZOLO [3, 4-B] PYRIDIN-3-Y 1) ETHANONE. LC-MS RT= 3. 3 min ES+ (274.0) ES- (272.1)
