Electric Literature of 1207518-63-5 ,Some common heterocyclic compound, 1207518-63-5, molecular formula is C8H6ClN3O2, 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.
General Procedure 5 Step 2: 4-Chloro-7-[(2R,3R,4R,5R)-3-ethynyl-3-hydroxy-4-(4-methyl- benzoyloxy)-5-(4-methyl-benzoyloxymethyl)-tetrahydro-furan-2-yl]-7H-pyrrolo[2,3- d]pyrimidine-5-carboxylic acid methyl ester; A dry flask is charged with 4-chloro-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylic acid methyl ester (698 mg, 3.3 mmol, 1.1 equiv.), NaH (156 mg as 60% dispersion in oil, 3.9 mmol) and acetonitrile (10 ml), stirring for 10 mins. Then crude compound 1 ,2-anhydro-2-C-ethynyl-3,5- bis(4-methylbenzoyl)-alpha-D-ribofuranose (1.2 g, 3.0 mmol) in acetonitrile (5 ml) is added and the reaction is heated at 80 0C for 3 h. The mixture is neutralized to pH = 7.0 by addition of 1 N HCI solution and evaporated under vacuum. Ethyl acetate (80 ml) is added and the mixture is washed with 1 N HCI solution (20 ml), H2O (20 ml), brine (20 ml), dried (Na2SO4), filtered, concentrated and purified by flash column to give 4-chloro-7-[(2R,3R,4R,5R)-3-ethynyl-3- hydroxy-4-(4-methyl-benzoyloxy)-5-(4-methyl-benzoyloxymethyl)-tetrahydro-furan-2-yl]-7H- pyrrolo[2,3-d]pyrimidine-5-carboxylic acid methyl ester. ESI-MS (pos.): 604.3 [M+H].
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1207518-63-5, its application will become more common.
