Related Products of 6345-27-3 , The common heterocyclic compound, 6345-27-3, name is Isonicotinimidamide hydrochloride, molecular formula is C6H8ClN3, 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: Anoven-dried 10mLvialwas charged with CuI (9mg, 0.05mmol),K3PO4 (318 mg, 1.5 mmol), pivalic acid (20 mg, 0.2 mmol), a 1-(2-bromophenyl)methanamine 1 (0.5 mmol), and an amidinium salt 2or an imidate salt 4 (0.5 mmol) under air. After sealing the vial, dry1,2-dichlorobenzene (3 mL) was added by syringe and the reactionmixture was stirred at 110 C (oil bath temperature) for 18 h. Aftercooling to room temperature, the vial was opened and the reactionmixturewas partitioned between CH2Cl2 (30 mL) and brine (20 mL).The aqueous phase was extracted with CH2Cl2 (220 mL). Thecombined organic layers were dried over anhydrous MgSO4 andconcentrated in vacuum. The residue was purified by flash chromatographyon silica gel to afford the desired product.
The synthetic route of 6345-27-3 has been constantly updated, and we look forward to future research findings.
