Reaction Steps

First, 2.81 g of 1-phenyl-4,6-dichloropyrazolo[3,4-d]pyrimidine was suspended in 60 ml of ethanol, then 3.2 g of (R)-(+)-2-amino-3-phenyl-1-propanol was added with stirring. After 48 hours the solvent was removed under vacuum and the oil was flash chromatographed (2-5-7% MeOH/CHCl3) to yield 3.80 g of (R)-β-[(1-phenyl-6-chloro-1H-pyrazolo[3,4-d]pyrimidin-4-yl)amino]benzenepropanol (95%).
