Procedure

To a solution of 5-(2,3-dihydro-benzo[1,4]dioxin-6-yl)-[1,2,4]triazolo[1,5-c]pyrimidin-2-ylamine (0.04 g, 0.148 mmol) in dry acetonitrile (2 mL) was added triethylamine (0.052 mL, 0.371 mmol) followed by cyclopropanecarbonyl chloride (0.034 mL, 0.371 mmol). The reaction mixture was then allowed to warm to ambient temperature, and the solvent removed under reduced pressure. The crude product was purified by preparatory HPLC. 1H NMR (300 MHz, DMSO): 1.84-1.88 (m, 4H), 2.00-2.08 (m, 1H), 4.31-4.36 (m, 4H), 7.06 (d, 1H), 7.64 (d, 1H), 8.21 (dd, 1H), 8.35 (d, 1H), 8.39 (d, 1H), 11.37 (s, 1H). LCMS Method: 2: RT: 3.51 min, MI: 338 [M+1].
