Procedure

Using 7-(2-chloro-4-fluorophenylamino)-6-[4-(4-fluorophenyl)piperidine-1-carbonyl]pyrazolo[1,5-a]pyrimidine-3-sulfonamide (0.10 g, 0.18 mmol) obtained in step 5 and cyclopropylisocyanate (0.046 g, 0.549 mmol) instead of ethylisocyanate, and in the same manner as in Example 7, the title compound (0.055 g, 47%) was obtained.
