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 acetyl chloride instead of chloromethylcarbonate. LCMS (0.05% TFA): 369.1 m/z (M+H)+; 1H-NMR (DMSO-d6, 500 MHz): δ: 9.71 (s, 1H), 8.43 (d, 1H, J=5.0 Hz), 8.27 (d, 1H, J=5.0 Hz), 8.25 (s, 1H), 4.59 (m, 1H), 4.49 (m, 1H), 3.38 (s, 3H), 2.26 (s, 3H), 1.92 (m, 1H), 1.80 (m, 1H), 1.47 (t, 6H, J=6 Hz), 0.81 (t, 3H, J=7.5 Hz).
