Procedure

Sodium hydride (0.875 g, 21.87 mmol) was added to (S)-2-hydroxy-N-(5-methylpyrazin-2-yl)-3-((R)-1-(triisopropylsilyloxy)propan-2-yloxy)propanamide (Intermediate AZ2) (3.0 g, 7.29 mmol) in anhydrous THF (35 mL) at 0° C. under nitrogen. The resulting solution was stirred at 0° C. for 10 minutes and then a solution of 1-(2-bromo-6-chlorophenyl)-4-chloro-1H-pyrazolo[3,4-d]pyrimidine (Intermediate BO2) (2.507 g, 7.29 mmol) in anhydrous THF (20 mL) was added dropwise over 1 minute. The mixture was stirred at 0° C. for 10minutes and then allowed to warm to ambient temperature for 6 hours.
