Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1003-21-0, name is 5-Bromo-1-methyl-1H-imidazole, This compound has unique chemical properties. The synthetic route is as follows., Quality Control of 5-Bromo-1-methyl-1H-imidazole
To a flask containing 5-bromo-1-methyl-1H-imidazole (345 mg, 2.14 mmol) was added THF (8 mL) and the solution was cooled to 0 C. To this clear homogeneous solution was added isopropylmagnesium chloride-LiCl complex (1.3 M, 2.0 mL, 2.6 mmol) which resulted in a white suspension. The reaction was stirred at 0 C. for 30 min, then a THF (2 mL) solution of N-methoxy-N,2-dimethylthiazole-4-carboxamide (250 mg, 1.34 mmol, Intermediate 38, step a) was introduced and the mixture became more viscous and was allowed to warm to room temperature. After 3 hours the mixture was quenched with saturated NH4Cl solution and extracted with EtOAc (4×50 mL). The combined organics were washed with brine, dried over Na2SO4, filtered and concentrated. Flash chromatography on silica gel (20-40% EtOAc-DCM increasing gradient to 5% MeOH-DCM) provided the title compound as an off-white solid.
According to the analysis of related databases, 1003-21-0, the application of this compound in the production field has become more and more popular.
