Versuchsvorschrift
In the same manner as in Example 21, step 5 and using 7-benzylamino-3-bromopyrazolo[1,5-a]pyrimidine-6-carboxylic acid (0.500 g, 1.44 mmol) obtained in Example 22, step 3 and 4-fluoro-4-phenylpiperidine (WO2002/13824, 0.340 g, 1.73 mmol), the title compound (0.630 g, 86%) was obtained.
