Related Products of 3680-69-1 ,Some common heterocyclic compound, 3680-69-1, molecular formula is C6H4ClN3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
To a solution of NaH (3 g, 0.13 mol) in DMF (60 mL)Suspension is slowSlow to join 1(10 g, 0.066 mol) in DMF (40 mL).The reaction mixture was stirred at 0 & lt; 0 & gt; CStirring for 2 hours,A light brown cloudy mixture was obtained.And then slowly added to the mixture2- (trimethylsilyl) ethoxymethyl chloride (SEMCl) (12.7 g, 0.08 mol)Stirred overnight at room temperature,The reaction was quenched with water and extracted with ethyl acetate,The filtrate was concentrated under reduced pressure. Purification by flash chromatography gave intermediate 2(15 g, 81%),As a pale yellow oil;
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,3680-69-1, its application will become more common.
