実験手順
The title compound was prepared from 5-(3-chloro-4-trifluoromethyl-phenyl)-7-trifluoromethyl-pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (example C.17) (205 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 (90 mg, 34%). MS (ISP) 526.1 [(M+H)+]; mp 234° C.
