Extracurricular laboratory: Synthetic route of 84703-18-4

With the rapid development of chemical substances, we look forward to future research findings about 84703-18-4.

As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 84703-18-4, name is 5-Bromo-2-chloro-6-methylnicotinonitrile, molecular formula is C7H4BrClN2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Recommanded Product: 84703-18-4

Step 1: 5-bromo-2-chloro-6-methylnicotinaldehyde (119b) To a solution of 5-bromo-2-chloro-6-methylnicotinonitrile (0.20 g, 0.86 mmol) in DCM (200 mL) was successively added DIBAL (0.86 mL, 1.30 mmol) at -78 C. under N2. The reaction mixture was stirred at room temperature for 2 h. the mixture was diluted with water and EtOAc. The organic layer was separated and the aqueous layer extracted with EtOAc. The residue was purified by column chromatography on silica gel to give 119b (20.0 g, 60.4%) as a yellow solid. LC-MS (ESI): m/z=233.9 [M+H]+

With the rapid development of chemical substances, we look forward to future research findings about 84703-18-4.
