実験手順

First, 1.13 g of the starting material 4-chloro-1-phenylpyrazolo[3,4-d]pyrimidine was combined with 0.67 ml Et3N, 0.74 g of (R)-(+)-2-amino-3-phenyl-1-propanol in 60 ml absolute ethanol and heated in a steam bath for four hours. The solvent was then removed under vacuum and the residue was purified by flash chromatography (10-20% isopropyl alcohol/hexane) to yield 1.24 g of (R)-β-[1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-yl)amino]benzenepropanol (74% yield).
