Synthetic Route of 10351-75-4,Some common heterocyclic compound, 10351-75-4, name is 1H-Benzo[d]imidazole-5,6-dicarboxylic acid, molecular formula is C9H6N2O4, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A mixture of Pb(NO3)2 (0.1 mmol, 33.1 mg), H3bidc (0.1 mmol, 20.6 mg) and phen (0.1 mmol, 18.0 mg) with H2O (8 mL) and methanol (2 mL) were adjusted to pH=7.0 with 1M sodium hydroxide and stirred 1 h. Then they were transferred into a 25 mL Teflon-lined stainless steel container, which were heated at 130 C for 72 h. After cooling to room temperature at a rate of 5 C/h, the block-like crystals of 1 were isolated by washing with distilled water several times and dried in air. The yield was about 40.8 % (based on H3bidc). Elem. Anal. Calcd. for C21H14PbN4O5 (%): C, 41.38; H, 2.32; N, 9.19. Found: C, 41.42; H, 2.39; N, 9.22.
The synthetic route of 10351-75-4 has been constantly updated, and we look forward to future research findings.
