| | 3,4,5,6-TETRAHYDRO-2-PYRIMIDINETHIOL Usage And Synthesis |
| Uses | Tetrahydropyrimidine-2(1H)-thione is a reactant in the preparation of aryl substituted heterocycles. | | Uses | Tetrahydropyrimidine-2(1H)-thione is a reactant in the preparation of aryl substituted heterocycles. | | Preparation | The preparation of 3,4,5,6-Tetrahydro-2- pyrimidinethiol is as follows:Carbon disulfide (0.2 mol) was added dropwise to a solution of 1,3-diamino propane 1 (0.2 mol) in H2O/EtOH (20 ml), and the temperature was remained constant at 0-5 oC. After the completion of addition, the reaction mixture was refluxed for 12h and then cooled to room temperature. The precipitate was collected by filtration and recrystallized from EtOH to give pure desired compound. |
