Procedure

To a solution of 4-{5-[2-chloro-7-methyl-8-(3-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-6-yl]-pyrazol-1-yl}-benzonitrile (Int. 19, 68 mg, 0.14 mmol) in NMP (2.5 mL) was added N,N-dimethyl-propane-1,3-diamine (54 μL, 0.43 mmol) followed by triethylamine (39 μL, 0.28 mmol). The reaction mixture was heated to 220° C. for 5 hrs using microwave irradiation. The cooled reaction mixture was concentrated in vacuo then loaded onto a SCX-2 cartridge (2 g) in MeOH. After washing with DCM/MeOH, the crude product was eluted with 2 M NH3 in MeOH and following concentration in vacuo gave a brown oil (53 mg). The oil thus obtained was purified using preparative TLC (20×20 cm×1 mm) eluting with 20% MeOH in DCM to give the title compound as a pale yellow oil, which solidified on standing (14 mg).
