Reaction Steps

To a mixture of 2-((1S,2R)-2-(piperidin-4-yl)cyclopropyl)ethanol (Intermediate 11; 70 mg, 0.4 mmol) and 2-bromo[1,2,4]triazolo[1,5-a]pyrimidine (9 mg, 0.496 mmol) in ethanol (2 mL) was added DIEA (0.22 mL, 1.21 mmol) and the resulting mixture heated via microwave to 120° C. for 1 hr. HPLC of the reaction mixture proved the reaction was complete with the absence of Intermediate 11. The mixture was filtered (glass wool filter paper, Whatman 1821 110), and washed with ethanol. The filtrate was concentrated to dryness under reduced pressure and the resulting residue purified via preparative TLC plates (2×1000 μM silica gel) eluting with 50% ethyl acetate in hexane. The product was removed from the silica gel by extracting with ethyl acetate and the solvent was removed under reduced pressure to afford the title compound as an off-white solid. MS (Multimode) m/z 288 [M+H]+.
