Some common heterocyclic compound, 10111-08-7, name is Imidazole-2-carboxaldehyde, molecular formula is C4H4N2O, 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. HPLC of Formula: C4H4N2O
To a solution of compound 1 H-imidazole-2-carbaldehyde (5g, 52.08 mmol) in MeOH (50 mL) was added sodium borohydride (3.93g, 104.16 mmol) portion-wise, at 5 00, and the reaction mixture was allowed to stir at RT for 3h. The reaction mixture was quenched with brine (25 mL) and concentrated in vacuo. The crude compound was purified by silica gel column chromatography eluting with 10% MeOH/CHCI3) to obtain (1H-imidazol-2-yl)-methanol as a pale yellow solid (4g, 78%).R:0.1 (10% MeOH/CHCI3).1H NMR (400MHz, CD3OD): O 6.97 (5, 2H), 4.61 (5, 2H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 10111-08-7, its application will become more common.
