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. 5750-76-5, name is 2,4,5-Trichloropyrimidine, molecular formula is C4HCl3N2, 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: 5750-76-5
To a degassed solution of 2,4,5-trichloropyrimidine (15.0 g, 81.8 mmol) in PEG 300 (91 mL) at room temperature under nitrogen atmosphere was added triethylamine (12.0 mL, 85.8 mmol), butyl vinyl ether (13.5 mL, 98.1 mmol) and palladium acetate (0.73 g, 3.3 mmol). The reaction mixture was stirred for 1.5 h at 80 C under nitrogen atmosphere. The reaction was cooled to room temperature, Et20 (250 mL) was added, and the layers were separated. The dark glycol layer was extracted with Et20 (4 x 90 mL). The combined Et20 layers were washed with water (4 x 90 mL), then dried over MgS04, filtered and concentrated to yield an orange oil. The residue was purified by Si02 chromatography (Hex/ Et20 0 to 30% gradient) and afforded the title compound as an orange oil (10.70 g, 43.2 mmol, 53%).
With the rapid development of chemical substances, we look forward to future research findings about 5750-76-5.
