88% | Stage #1: With sodium In ethanol at 20℃; for 4 h; Inert atmosphere Stage #2: for 1 h; Inert atmosphere; Reflux |
General procedure: Metallic sodium (12.9 g, 0.56 mol) was dissolved in absolute ethanol (300 mL) under argon while being intensively stirred with a mechanical stirrer. The reaction flask was equipped with a reflux condenser with a chlorocalcium tube. After all the sodium was dissolved and the reaction mixture was cooled to room temperature; guanidine hydrochloride(21.02 g, 0.22 mol) was added under intensive stirring, followed by the corresponding monosubstituted malonic acid diester (0.2 mol). The reaction mixture was further intensively stirred due to the production of the solid product,which is so massive that after 2 h it already practically precludes stirring. After another 2 h, absolute ethanol (200 mL) was added and the reaction mixture was refluxed for 1 h while being stirred. Afterward, ethanol (ca200–300 mL) was evaporated on a vacuum rotary evaporatorand water (500 mL) was added to the reaction mixture. After stirring, the product (in the form of sodium salt) was almost dissolved. The obtained mixture was subsequently neutralized by dropwise addition of acetic acid, resulting in immediate and quantitative precipitation of the desired product in the form of a fine solid. This mixture was subsequently heated under reflux for 10 min and then cooled to laboratory temperature. This heating and cooling was repeated twice to get a well-filterable solid product. The solid product was filtered off, washed with water (2 x 50 mL),ethanol (2 x 50 mL), and acetone (2 x 50 mL). The product was dried under high vacuum at 60 °C for 2 days. The obtained purity of the product prepared in this manner is sufficient for the following reaction and based on analyses contains only crystalline water. |

With sodium methylate; In ethanol;Reflux; | Intermediate compound 12 (Scheme 1B) was prepared by a 2-step procedure reported by Taylor et al.?2 Acetol 10 was condensed with malononitrile in the presence of triethylamine in methanol to afford <strong>[5117-87-3]2-amino-3-cyano-4-methylfuran</strong> (compound 11) which was condensed with guanidine hydrochloride in presence of sodium methoxide to give intermediate (compound 12) in 44% yield. The synthesis of target compounds 2-9, outlined in Scheme 1B, involved oxidative thiolation of the common intermediate 2,4-diamino-5 -methyl-pyrrolo [2,3-d]pyrimidine (compound 12) with appropriately substituted thiols. Compounds 2-5 were synthesized from compound 12 with slight modification of the oxidative thiolation previously reported by Gangjee et al.?3 This procedure involved reacting compound l2with appropriately substituted thiols and iodine in a 2:1 mixture of ethanol and water at reflux to give compounds 2-5. Compounds 6-9 were synthesized by methylation of the pyrrole nitrogen using sodium hydride and iodomethane. |
