phenylalaninol, (S)- → (S)-beta-[(1-phenyl-6-chloro-1H-pyrazolo[3,4-d]pyrimidin-4-yl)amino]benzenepropanol

Participants

Reaction Steps

2.5 g of the starting material 1-phenyl-4,6-dichloropyrazolo[3,4-d]pyrimidine was suspended in 60 ml of ethanol. Next, 4.28 g of (S)-(-)-2-amino-3-phenyl-1-propanol was added and the reaction was allowed to stir for 24 hours. The solvent was then removed under vacuum and the crude oil was purified by flash chromatography (10-15-20% isopropyl alcohol/hexane) to yield 3.5 g of (S)-β-[(1-phenyl-6-chloro-1H-pyrazolo[3,4-d]pyrimidin-4-yl)amino]benzenepropanol (97%).
