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 methane sulfonylchloride instead of chloromethylcarbonate. LCMS (0.05% TFA): 405.2 m/z (M+H)+; 1H-NMR (DMSO-d6, 500 MHz): δ: 12.77 (bs, 1H), 8.89 (bs, 1H), 8.50 (bs, 1H), 8.41 (s, 1H), 8.23 (s, 1H), 4.55 (m, 1H), 4.49 (m, 1H), 3.34 (s, 3H), 3.26 (s, 3H), 1.87 (m, 1H), 1.77 (m, 1H), 1.44 (bs, 6H), 0.75 (bs, 3H).
