Procedure

To a solution of the title D compound of Example 1, 2-{5-amino-2-(furan-2-yl)-7H-pyrrolo[3,2-e][1,2,4]triazolo[1,5-c]pyrimidin-7-yl}ethyl methanesulfonate (0.06 g, 0.165 mmol) in dry DMF (5 mL), 4-(2,4-difluorophenyl)piperidine (0.33 mmol) and 0.06 mL of DIEA are added, and the solution is stirred at 100° C. for 5 h. The reaction mixture is cooled to RT, and the solvent is removed under reduced pressure. The crude product is purified by flash chromatography using a 95/5.0/0.5-mixture of DCM/MeOH/NH4OH as an eluent to give 7-(2-(4-(2,4-difluorophenyl)piperidin-1-yl)ethyl)-2-(furan-2-yl)-7H-pyrrolo[3,2-e][1,2,4]triazolo[1,5-c]pyrimidin-5-amine: LC/MS (M+1=463.98). 1H NMR (DMSO-d6, 400 MHz), δ 1.68 (m, 4H), 2.12 (m, 2H), 2.55 (m, 1H), 2.73 (t, 2H, J=6.0 Hz), 3.04 (m, 2H), 4.26 (t, 2H, J=6.4 Hz), 6.59 (d, 1H, J=3.6 Hz), 6.71 (m, 1H), 7.09 (m, 1H), 7.18 (m, 2H), 7.26 (m, 1H), 7.33 (m, 1H), 7 49 (br s, 2H, NH2), 7.91 (s, 1H).
