In a sealed flask, a solution of the crude 6-(2,4-dichloro-phenyl)-3-morpholin-4-yl-[1,2,4]triazolo[4,3-a]pyridine-7-carbonitrile in THF (1 mL) was cooled to 0° C. (ice bath) then treated with BH3.THF complex (1.0 M solution in THF, 0.73 mL, 0.73 mmol). The reaction mixture was heated at 40° C. for 1 h, cooled to RT, and diluted in MeOH (large excess). The mixture was concentrated under vacuum, and the remaining residue was suspended in 2.0 M HCl, and shaken for 15 min. After evaporation to dryness, the remaining residue was purified by reverse phase prep-HPLC (Waters system) to give the title compound (2TFA salt, 5 mg, 0.008 mmol, 5%) as a white solid. MS: 378 [M+1]+; HPLC: AtRet=1.15.
