Reaction Steps

To 4-chloro-2-morpholin-4-yl-7-pyridin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidine (10 mg, 0.0315 mmol), 3-cyano-4-fluorophenylboronic acid (10.4 mg, 0.0630 mmol), palladium acetate (1.4 mg, 0.0063 mmol), S-Phos (5.2 mg, 0.0126 mmol) and sodium hydroxide (2.5 mg, 0.063 mmol), t-butanol (1 ml) was added, followed by being degassed under ultrasonic irradiation. This was stirred at 100° C. for 3 hours, followed by extraction with ethyl acetate with the addition of water, and the organic layer was washed with brine. After drying over anhydrous sodium sulfate, concentration was carried out under reduced pressure, followed by elution with 2M ammonia methanol solution through SCX resin and then concentration. Purification by preparative TLC afforded the desired compound as a colorless solid (3.1 mg, yield 12%).
