The title compound was prepared similarly to the methods described in Example 102, with (R)-2-(3-(aminomethyl)pyridin-4-yl)-8-cyclopentyl-7-ethyl-5-methyl-7,8-dihydropteridin-6(5H)-one (Example 105) instead of (R)-2-(3-aminopyridin-4-yl)-8-cyclopentyl-7-ethyl-5-methyl-7,8-dihydropteridin-6(5H)-one (Example 91), and with acetic acid instead of benzoic acid. LCMS (0.05% TFA): 409.2 m/z (M+H)+; 1H-NMR (CDCl3, 500 MHz): δ: 8.98 (bs, 1H), 8.82 (d, 1H, J=5.0 Hz), 8.39 (d, 1H, J=5.0 Hz), 8.05 (s, 1H), 7.31 (bs, 1H), 4.84 (s, 2H), 4.46 (m, 1H), 4.37 (m, 1H), 3.44 (s, 3H), 2.03 (m, 1H), 1.95 (s, 3H), 1.94˜1.68 (m, 9H), 0.91 (t, 3H, J=7.5 Hz).
