5.115 PYRIMIDINE-5-CARBOXYLIC ACID [2-(2,6-DIOXOPIPERIDIN-3-YL)-1,3-DIOXO-2,3-DIHYDRO-1H-ISOINDOL-4-YLMETHYL]AMIDE A mixture of pyrimidine-5-carboxylic acid (0.25 g, 2.0 mmol) and CDI (0.39 g, 2.4 mmol) in DMF (25 mL) was stirred at ambient temperature under nitrogen for 2 hours. 4-Aminomethyl-2-(2,6-dioxopiperidin-3-yl)isoindole-1,3-dione hydrochloride (0.65 g, 2.0 mmol) and triethylamine (0.61 g, 6.0 mmol) were added, and the mixture was allowed to stir for 16 hours. The solvent was evaporated under vacuum, and the residue was chromatographed using a methylene chloride-methanol gradient, eluting with 95:5 methylene chloride-methanol, providing 0.39 g of the product in 50percent yield: mp >260° C.; 1H NMR (DMSO-d6) delta 2.05-2.10 (m, 1H), 2.53-2.65 (m, 2H), 2.83-2.91 (m, 1H), 4.98 (d, J=5.7 Hz, 2H), 5.18 (dd, J=12.4 Hz, d=5.4 Hz, 1H), 7.84 (s, 3H), 9.24 (s, 2H), 9.35 (s, 1H), 9.52 (t, J=5.7 Hz, 1H), 11.16 (s, 1H); 13C NMR (DMSO-d6) delta 22.0, 30.9, 38.3, 48.9, 122.1, 127.3, 127.5, 131.6, 133.4, 134.9, 138.4, 156.0, 160.1, 163.5, 167.0, 167.5, 169.8, 172.8; Anal. calcd for C19H15N5O5.0.3H2O: C, 57.23; H, 3.94; N, 17.56. Found: C, 57.27; H, 3.71; N, 17.27.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 4595-61-3, Pyrimidine-5-carboxylic acid.
