Reaction Steps

2-{(1S,2S)-2-[1-(5-chloropyrimidin-2-yl)piperidin-4-yl]cyclopropyl}ethanamine (50 mg, 0.18 mmol) from step 3, Example 5 and 2-chloro-5-(1H-1,2,4-triazol-1-yl)pyrazine (35.6 mg, 0.20 mmol) were added in NMP (0.89 mL), then potassium carbonate (73.8 mg, 0.53 mmol) was added and the reaction was heated to 90° C. overnight. The reaction was cooled to room temperature, water (10 mL) was added and drops of acetic acid were added to adjust pH value to ˜4, extracted with ethyl acetate (20 mL), second wash with brine (10 mL). The water phase was back extracted with ethyl acetate (10 mL×2). The organic phase were combined and dried by magnesium sulfate, filtered and concentrated and purified by column chromatography through a 25 gram Biotage SNAP KP-Sil™ silica gel cartridge eluting with 30% ethyl acetate/hexane to give the title compound as a white solid.
