4-Chloromethyl-3,5-dimethyl-isoxazole (1.5 eq.) was directly added to a solution of 7-furan-2-yl-2-piperazin-1-yl-pyrazolo[1,5-a][1,3,5]triazin-4-ylamine (0.14 mmol) and Et3N (0.3 mmol) in 3 mL of CH3CN. The resulting reaction mixture was stirred at room temp for 18 hours. It was then concentrated and purified by preparative HPLC using a mixture of aqueous CH3CN that has been buffered with 0.1% TFA. 1H NMR (DMSO-d6) δ 7.60 (d, J=1.0 Hz, 1 H), 7.28 (br s, 2H), 7.22 (d, J=3.6 Hz, 1H), 6.68 (dd, J=3.6 Hz, 1.0 Hz, 1 H), 6.2 (s, 1H) 3.8 (br s, 2H), 2.2-3.2 (m, 8H), 1.6 (br s, 6H). MS: m/z: 395 [M+H]+.
