実験手順

A mixture of 5-[7-trifluoromethyl-5-(4-trifluoromethyl-phenyl)-pyrazolo[1,5-a]pyrimidin-3-ylethynyl]-pyridin-2-ylamine (example 55) (2.00 g, 4.47 mmol) in acetic anhydride (15 mL) was stirred at 120° C. for 1 h. Cooled to 60° C., concentrated in vacuum to dryness (water bath temperature 60° C.) and dried in HV to give an orange solid (2.465 g, 113%, mixture of mono- and diacetylated compound). Suspended in THF (30 mL) at 23° C., added NH4OH (25%, 13.3M, 1.0 mL, 13.4 mmol) and stirred at 23° C. for 1.5 h resulting in a clear red solution, adjusted pH with 1N HCl until pH 1, added H2O (total volume 200 mL), filtered the precipitate off, washed with H2O and dried in HV, followed by trituration with ether and drying in HV to give the title compound as an orange solid (2.130 g, 97%). MS [ISN] 488.1 [(M−H)−]; mp 266° C.
