Tag: 3682-14-2

As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO104,mainly used in chemical industry, its synthesis route is as follows.,3682-14-2

A solution of 400 mg (1.44 mM) of 4-chloro-6,7-diethoxy-quinoline-3-carbonitrile and 273 mg (1.54 mM) of 4-Aminophthalhydrazide Hydrate in 15 ml of 2-methoxyethanol was refluxed for 3 hours. To the warm solution was added 1 ml of 1M sodium carbonate and the sample was heated for 5 minutes at 100C, then poured into 300 ml of ice water. The solution was made acetic by addition of concentrated HCl and the solid was collected, washed with water followed by ether and dried under vacuum at 80C. The solid was taken up into 200 ml of methanol and 500l of 5 N sodium hydroxide and boiled for 20 minutes. To this heterogeneous mixture was added 100 ml of glacial acetic acid and the volume was reduced to a total of 100 ml by boiling. To the room temperature mixture, 500 ml of ice cold water was added and the solid was collected, washed with water followed by ether and dried under vacuum at 80C. The solid was digested in 400 ml of ethanol until the volume had been reduced to 150 ml. The hot solution was filtered and the solid was washed with ethanol and to dried under vacuum at 80C yield 121 mg of the title compound as a white solid: mass spectrum (electrospray, m/e): M+H 418.0, mp = >270C.

With the complex challenges of chemical substances, we look forward to future research findings about 6-Amino-2,3-dihydrophthalazine-1,4-dione,belong phthalazine compound

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.3682-14-2,6-Amino-2,3-dihydrophthalazine-1,4-dione,as a common compound, the synthetic route is as follows.

Example 334: Preparation of 6-((4-(cyclopropyIamino)-5-(trifluoromethyl)pyrimidin-2- yl)amino)-2,3-dihydrophthalazine-l,4-dione2-Chloro-N-cyclopropyl-5-(trifluoromethyl)pyrimidin-4-amine (0.055 g, 0.231 mmol) and 6-amino-2,3-dihydrophthalazine-1 ,4-dione (0.041 g, 0.231 mmol) were mixed in acetic acid (2 ml). The mixture was microwaved at 1 10 ¡ãC for 20 min and then concentrated. Added MeOH and 5percent DMF and filtered the solid to give 35 mg of product. MS calcd for [Ci6H13F3N602+H]+: 379.12, found 379.00.

As the paragraph descriping shows that 3682-14-2 is playing an increasingly important role.
