Boronic Acid → 2,6-difluoro-3-(2-morpholin-4-yl-7-pyridin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidin-4-yl)-benzaldehyde

Participants

Reaction Steps

In the same manner as Example 1-B-10, using 4-chloro-2-morpholin-4-yl-7-pyridin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidine, and 2,4-difluoro-3-formylphenylboronic acid as a boronic acid, 2,6-difluoro-3-(2-morpholin-4-yl-7-pyridin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidin-4-yl)-benzaldehyde was obtained. Methanol and sodium borohydride were added, which was stirred at room temperature for 1 hour, 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.
