Reaction Steps

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), 2,4-difluorobenzenethiol (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. To the residue, acetonitrile is added and the solution is stirred at 60° C. for 0.5 h. The solution is then cooled to RT, and the resulting solids are collected by filtration to give 7-(2-(2,4-difluorophenylthio)ethyl)-2-(furan-2-yl)-7H-pyrrolo[3,2-e][1,2,4]triazolo[1,5-c]pyrimidin-5-amine: LC/MS (M+1=412.91). 1H NMR (DMSO-d6, 400 MHz) δ 3.40 (m, 2H), 4.32 (m, 2H), 6.56 (m, 1H), 6.72 (m, 1H), 7.05 (m, 1H), 7.12 (m, 1H), 7.22 (m, 2H), 7.53 (m, 3H), 7.92 (s, 1H). Anal. calculated for (C19H14F2N6OS): C, 55.33; H, 3.42; F, 9 21; N, 20 38; O, 3.88; S, 7.77. Found C, 55.01; H, 3 75; N, 21.95; S, 6.89.
