Reaction Steps

3-Bromo-7-{[2-chloro-3-(trifluoromethyl)phenyl]carbonyl}-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyrazine (0.075 g, 0.183 mmol, e.g. see Example 1 for methods of preparation) was treated with morpholine (1.5 mL) and heated in a microwave reactor at 110° C. for a total of 7 hours. The solvent was evaporated under reduced vacuum and the residue was purified by mass-directed automated (preparative) HPLC (MDAP) and triturated with isohexane to afford 7-{[2-chloro-3-(trifluoromethyl)phenyl]carbonyl}-3-(4-morpholinyl)-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyrazine (0.012 g) as white solid.
