651780-27-7,The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a downstream synthesis route of the compound 651780-27-7
651780-27-7, 10% Palladium on carbon (1.5g) and triethylamine (7.5 g, 82.4 mmol) were added to a solution of ethyl 6-bromobenzisoxazole-3-carboxylate (20g, 0. 081mol) in ethanol (300ml) at 0 C under an atmosphere of nitrogen. The nitrogen atmosphere was removed by evacuation and replaced with hydrogen gas, and the reaction mixture was maintained for 1 hour. The hydrogen atmosphere was removed by evacuation and replaced with nitrogen gas, and the palladium removed by filtration through Celite. The filter cake was washed with ethanol (3 x 50 mL) and the filtrates were concentrated. The residue was dissolved in dichloromethane (200 mL) and the solution was washed with water (4 x 50 mL), dried (sodium sulfate) and evaporated to provide 13.0 g of the product as a yellow solid (96%). The ester was saponified using sodium hydroxide to provide the acid. The acid was coupled with the bicyclobase according to procedure A. Literature reference: Angell, R. M.; Baldwin, I. R.; Bamborough, P.; Deboeck, N. M.; Longstaff, T.; Swanson, S. W004010995A1 The following acid was prepared using this method: 1,2-Benzisoxazole-3-carboxylic acid.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about Ethyl 6-bromobenzo[d]isoxazole-3-carboxylate.
