Application of 614-97-1, A common heterocyclic compound, 614-97-1, name is 5-Methyl-1H-benzo[d]imidazole, molecular formula is C8H8N2, its 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.
General procedure: Equivalent amount of the N-protected amino acid or dipeptide (1.45 mmol) (2a: 300 mg, 2b: 320 mg, 2c: 440 mg, 2d: 480 mg, 2e: 250 mg, 2f: 390 mg, 2g: 300 g, 2h: 440 mg, 2i: 250 mg, 2j: 390 mg, 2k: 300 mg, 2l: 320 mg, 2m: 440mg, 2n: 480 mg, 2o: 390 mg, 2p: 520 mg), benzimidazole (or its derivative) (1.45 mmol), (2a, 2b, 2c, 2d, 2e, 2f: 170mg, 2g, 2h, 2i, 2j: 190 mg, 2k, 2l, 2m, 2n, 2o: 240 mg, 2p:170 mg) and DCC (300 mg, 1.45 mmol) were reacted in dried THF (10 mL) under an atmosphere of argon for 3 h at room temperature and formed dicyclohexzylurea was filtered off. The volatiles were removed with reduced pressure. The residue was crystallized from ethanol/diethyl ether (1:2) (Fig. 1).
The synthetic route of 614-97-1 has been constantly updated, and we look forward to future research findings.
