701-16-6, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 5-Fluoro-2-methylbenzo[d]oxazole, cas is 701-16-6,the benzoxazole compound, it is a common compound, a new synthetic route is introduced below.
General procedure: The SBOs were prepared by the base-catalysed condensation of the appropriate 5-halogeno-2-methylbenzoxazole with the requisite aromatic aldehyde under phase transfer conditions. In a typical experiment, equimolar quantities (5 mmol) of the starting materials were dissolved in dichloromethane (20-50 ml) in the presence of benzyltriethylammonium chloride (3 mmol) and stirred magnetically under a nitrogen atmosphere as an aqueous solution of sodium hydroxide (50%, w/v, 5 ml) was added dropwise over a period of 10 min. After being stirred for 2-36 h until analytical thin layer chromatography indicated that the reaction was complete, the mixture was diluted with water (50 ml) and the SBO was extracted with dichloromethane (3×20 ml), dried (MgSO4), filtered, evaporated under reduced pressure and recrystallized from aqueous methanol or ethanol.
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 5-Fluoro-2-methylbenzo[d]oxazole, 701-16-6
