Participants

Reaction Steps

In the same manner as in Example 1, step 6 and using 7-(3-fluorobenzylamino)-6-(4-phenylpiperidine-1-carbonyl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (0.09 g, 0.18 mmol) obtained in Example 6, step 2 and ethanesulfonamide (0.11 g, 1.08 mmol) instead of methanesulfonamide, compound a-7 (0.04 g, 38%) was obtained.
