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.

Adding a certain compound to certain chemical reactions, such as: 1207518-63-5, Methyl 4-chloro-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylate, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 1207518-63-5, blongs to pyrimidines compound. name: Methyl 4-chloro-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylate

Example 44; (4-Chloro-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-methanol (44.1); To a suspension of 4-Chloro-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylic acid methyl ester (example 43) (1.0 g, 4.716 mmol) in dichloromethane (60.0 mL) cooled to -780C, is added a solution of DIBAL-H (1.0 M in toluene, 14.15 mL, 14.15 mmol) dropwise. The resulting solution is stirred at -780C for 2 h and then at room temperature until TLC analysis indicates complete consumption of intermediate 43.2 (3 h). The reaction is quenched with aqueous NH4CI and stirred for 10 min. The salts separated are filtered off and the filtrate is washed with water, brine, dried over anhydrous Na2SO4 and concentrated in vacuo. The crude residue is impregnated over silica gel using methanol and the impregnated silica gel is loaded onto a silica gel column. Elution with a solvent gradient of CH2CI2 : MeOH = 90: 10 followed by evaporation of the eluted solvent gives intermediate 44.1 as a brown solid. 1H NMR (400 MHz, CDCI3): delta 12.35 (brs, 1 H), 8.54 (s, 1 H), 7.54 (s, 1 H), 5.01 (t, J = 5.07 Hz, 1 H), 4.75 (d, J = 5.07 Hz, 1 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.
