Reaction Steps

The title compound was prepared similarly to the methods described in Example 114, with (R)-2-(3-aminopyridin-4-yl)-7-ethyl-8-isopropyl-5-methyl-7,8-dihydropteridin-6(5H)-one (Example 93) instead of (R)-2-(3-aminopyridin-4-yl)-8-cyclopentyl-7-ethyl-5-methyl-7,8-dihydropteridin-6(5H)-one (Example 91) and with benzene sulfonylchloride instead of chloromethylcarbonate. LCMS (0.05% TFA): 467.2 m/z (M+H)+; 1H-NMR (DMSO-d6, 500 MHz): δ: 12.90 (s, 1H), 8.77 (s, 1H), 8.42 (d, 1H, J=5 Hz), 8.23 (s, 1H), 8.10 (d, 1H, J=5.5 Hz), 7.68 (d, 2H, J=7.5 Hz), 7.56 (t, 1H, J=7.5 Hz), 7.45 (t, 2H, J=7.5 Hz), 4.47 (m, 2H), 3.35 (s, 3H), 1.87 (m, 1H), 1.75 (m, 1H), 1.39 (d, 6H, J=6.5 Hz), 0.77 (t, 3H, J=7.5 Hz).
