Reaction Steps

The title compound was prepared in analogy to the procedure described for Example 17 but 2-bromo-6-(4-chloro-phenyl)-5-(1,3-dimethyl-2-oxo-hexahydro-pyrimidin-5-yl)-1-isopropyl-5,6-dihydro-1H-pyrrolo[3,4-b]pyrrol-4-one (Intermediate P) and 2,4-dimethoxypyridine-5-boronic acid were used instead of 2-bromo-5-(5-chloro-2-methyl-phenyl)-6-(4-chloro-phenyl)-1-isopropyl-5,6-dihydro-1H-pyrrolo[3,4-b]pyrrol-4-one and 5-cyano-2-methoxyphenylboronic acid respectively. The title compound was obtained as a white solid. tR: 2.95 min (HPLC 5); ESI-MS: tR=0.99 min, [M+H]+539/541 (LC-MS 1); 1H-NMR (d6-DMSO, 400 MHz): 8.26 (s, 1H), 7.51 (m, 2H), 7.24-7.48 (m, 2H), 6.25 (s, 1H), 5.85 (s, 1H), 4.08 (m, 1H), 3.95 (s, 3H), 3.90 (m, 1H), 3.89 (s, 3H), 3.81 (m, 1H), 3.23 (m, 1H), 3.11 (m, 1H), 2.93 (m, 1H), 2.70 (s, 3H), 2.61 (s, 3H), 1.28 (m, 3H), 0.40 (m, 3H).
