Some common heterocyclic compound, 57090-88-7, name is 1H-Imidazole-4-carbonitrile, molecular formula is C4H3N3, 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. Recommanded Product: 1H-Imidazole-4-carbonitrile
a) 1-(2-Trimethylsilanyl-ethoxymethyl)-1H-imidazole-4-carbonitrile A flask charged with imidazole-4-carbonitrile (0.50 g, 5.2 mmol) (Synthesis, 677, 2003), 2-(trimethylsilyl)ethoxymethyl chloride (SEMCl) (0.95 mL, 5.3 mmol), K2CO3 (1.40 g, 10.4 mmol), and acetone (5 mL) was stirred for 10 h at RT. The mixture was diluted with ethyl acetate (EtOAc) (20 mL) and washed with water (20 mL) and brine (20 mL) and the organic layer dried over MgSO4. The crude product was eluted from a 20-g SPE cartridge (silica) with 30percent EtOAc/hexane to give 0.80 g (70percent) of the title compound as a colorless oil: Mass spectrum (CI (CH4), m/z) Calcd. for C10H17N3OSi, 224.1 (M+H), found 224.1.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 57090-88-7, its application will become more common.
