Participants

Reaction Steps

Using 4-hydroxypyrazolo[3,4-d]pyrimidine (140 mg, 1.0 mmol), phosphorus oxichloride (3.0 ml), and dimethylaniline (0.39 ml, 3.1 μmol), and then 2-aminoindan (400 mg, 3.0 mmol), a similar procedure to Preparation Example 5 was carried out. The product obtained was purified by silica gel chromatography (hexane:ethyl acetate=5:2) to obtain the title compound (150 mg, 0.56 mmol) having the following physical properties:
