Procedure

A solution of {5-[5-ethyl-1-(tetrahydro-pyran-2-yl)-1H-pyrazol-4-yl]-[1,2,4]triazolo[1,5-a]pyrazin-8-yl}-(4-morpholin-4-yl-phenyl)-amine and {5-[3-ethyl-1-(tetrahydro-pyran-2-yl)-1H-pyrazol-4-yl]-[1,2,4]triazolo[1,5-a]pyrazin-8-yl}-(4-morpholin-4-yl-phenyl)-amine (40 mg, 0.077 mmol) and conc. HCl (0.3 mL) in MeOH (10 mL) is stirred at room temperature for 5 hours. After removing the solvent, the solid residue is partitioned between ethyl acetate and sat. NaHCO3. The undissolved solid is collected by filtration, washed with water, diethyl ether and petroleum ether and dried to afford the title compound (5 mg, 17%). Conversion into the mesylate salt using 0.1M methanesulfonic acid (0.128 mL) affords the title compound (5.6 mg, 89%) as a solid.
