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. 1196152-38-1, name is 2-Bromo-5-(trifluoromethyl)pyrazine, This compound has unique chemical properties. The synthetic route is as follows., Formula: C5H2BrF3N2
Description 67: 1,1-dimethylethyl (lR,4S,6R)-4-({[5-(trifluoromethyl)-2- pyrazinyl]oxy}methyl)-3-azabicyclo[4.1.0]heptane-3-carboxylate (D67); To a solution of 1,1-dimethylethyl (lR,4S,6R)-4-(hydroxymethyl)-3- azabicyclo[4.1.0]heptane-3-carboxylate D20 (120 mg) and 2-bromo-5- (trifluoromethyl)pyrazine D66 (120 mg) in DMF (4 ml) at 00C (ice bath) was added NaH (31.7 mg, 0.792 mmol) (gas evolution). The reaction mixture was slowly warmed to room temperature and stirred at room temperature for 1 hour. The reaction was quenched by a slow and careful addition of a saturated aqueous solution of NaHCO3 (40 ml). The organic phase was extracted with DCM (3×50 ml); the joined organic phase was washed with water and brine, dried over Na2SO4, filtered and concentrated to give the crude material. This was purified by Silica Chromatography (Biotage SP – column size 25 g) using Cy/EtOAc 90:10 as eluent. The appropriate fractions were concentrated to obtain the title compound D67 (62 mg).UPLC (Basic GEN_QC): rt = 1.07 minutes, peak observed: 374 (M+l) C17H22F3N3O3 requires 374.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 1196152-38-1.
