With sulfuric acid; In acetonitrile; at 20℃; for 2h;Heating / reflux; | Example 3; Preparation of <strong>[941678-49-5](R)-3-(4-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl)-3-cyclopentylpropanenitrile</strong> sulfuric acid saltTo a test tube was added <strong>[941678-49-5](R)-3-(4-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl)-3-cyclopentylpropanenitrile</strong> (153.0 mg) and sulfuric acid (56.1 mg) followed by acetonitrile (7.0 mL). The resulting mixture was heated to clear, cooled to room temperature, and then stirred for another 2 hours. The precipitate was collected by filtration and the cake was washed with 0.8 mL of cold acetonitrile. The cake was dried under vacuum to constant weight to provide the final salt product (180 mg).The sulfuric acid salt was shown to be a 1:1 salt by 1H NMR and crystallinity was confirmed by X-ray powder diffraction (XRPD). Differential scanning calorimetry (DSC) gave a sharp melting peak at about 186.78 C. The product showed little weight loss up to 175 C. by TGA. | |
180 mg | With sulfuric acid; In acetonitrile; at 20℃;Heating; | To a test tube was added (3R)-3-Cyclopentyl-3-[4-(7H-pyrrolo[2,3-d]pyrimidin- 4-yl)-lH-pyrazol-l-yl]propanenitrile (153.0 mg) and sulfuric acid (56.1 mg) followed by acetonitrile (7.0 mL). The resulting mixture was heated to clear, cooled to room temperature, and then stirred for another 2 hours. The precipitate was collected by filtration and the cake was washed with 0.8 mL of cold acetonitrile. The cake was dried under vacuum to constant weight to provide the final salt product (180 mg). |
