実験手順

The title compound was prepared similarly to the methods described in Example 114, 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 benzene sulfonylchloride instead of chloromethylcarbonate. LCMS (0.05% TFA): 507.2 m/z (M+H)+; 1H-NMR (MeOD, 500 MHz): δ: 8.82 (s, 1H), 8.76 (bs, 1H), 8.27 (d, 1H, J=5.0 Hz), 8.13 (s, 1H), 7.81 (d, 2H, J=8.0 Hz), 7.62 (t, 1H, J=8 Hz), 7.55 (t, 2H, J=8 Hz), 4.63 (s, 2H), 4.43 (m, 2H), 3.43 (s, 3H), 2.06˜1.65 (m, 10H), 0.88 (t, 3H, J=7.5 Hz).
