With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.99970-84-0,[2,2′-Bipyridine]-4,4′-dicarbaldehyde,as a common compound, the synthetic route is as follows.
99970-84-0, A mixture of 4,4′-diformyl-2,2′-bipyridine (234 mg,1.10 mmol) and 5-amino-1,10-phenanthroline (669 mg,3.43 mmol) in ethanol (50 mL) was heated to 80 C for12 h, giving a suspension. The reaction mixture was filtered hot, and the solid was washed with hot ethanol, affording the desired product as a yellow solid. Yield:486 mg (78 %). ESI-MS: m/z = 567.4 (M + H)+. 1HNMR (400 MHz, CDCl3): d = 7.68 (dd, J = 8.0, 4.8 Hz,2H), 7.74 (dd, J = 8.0, 4.4 Hz, 2H), 8.07 (dd, J = 5.2,1.2 Hz, 2H), 8.29 (dd, J = 2.8, 1.6 Hz, 2H), 8.31 (dd,J = 3.2, 1.6 Hz, 2H), 8.83 (dd, J = 8.4, 1.6 Hz, 2H), 8.88(s, 2H), 8.98 (d, J = 4.8 Hz, 2H), 9.07 (s, 2H), 9.19 (dd,J = 4.4, 2.0 Hz, 2H), 9.28 (dd, J = 4.4, 2.0 Hz, 2H). IR numax (KBr, cm-1): 3417 (br), 1628m, 1597s, 1554m,1505w, 1424m, 1383s, 1297w, 1206w, 1143w, 1062m,987w, 805w, 741s, 708w, 623w, 541w. Found: C 76.0, H3.8, N 19.7; Calcd for C36H22N8: C 76.3, H 3.9, N 19.8 %.
The synthetic route of 99970-84-0 has been constantly updated, and we look forward to future research findings.
