A solution of 3-(trifluorometliyl)-lH-pyrazol-5-amine (1 equic.) in 1,4-dioxane (0.2 M) was treated with 1,3-dibromopropane (1.2 equiv.) and triethylamine (5 equiv.) at 0 C and the reaction mixture was heated to 100 C for 12 h. After completion, reaction mixture was cooled to room temperature, filtered under reduced pressure and concentrated to afford crude product. The crude product was purified by flash chromatography to afford the product. 1H NMR (400 MHz, DMSO-d6): 12.25 (brs, IH), 6.40 (s, IH), 5.52 (s, IH), 4.03-4.00 (t, 2H), 3.58 (s, IH), 3.18-3.15 (m, 2H), 2.05-1.97 (m, 2H). LC-MS: MS m/z 192 [M+H]+.
