Procedure
The title compound was prepared from 5-(3,4-dichloro-phenyl)-7-difluoromethyl-pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (example C.7) (179 mg, 0.5 mmol) and 6-amino-N-hydroxy-nicotinamidine (example B.4) (114 mg, 0.75 mmol) according to general procedure II. Obtained after flash chromatography on silica gel (ethyl acetate/heptane) and further purification by crystallization (dichloromethane/hexane) as a yellow solid (92 mg, 39%). MS (ISP) 473.9 [(M+H)+]; mp 279° C.
