Reference of 3764-01-0, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 3764-01-0, name is 2,4,6-Trichloropyrimidine, molecular formula is C4HCl3N2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Method 1; Preparation of 2,4-dimorpholino-6-chloropyrimidine; [0234] To a dry round bottom flask was added 2,4,6-trichloropyrimidine (5 g, 27 mmol) and EtOH (200 mL), followed by DIEA (16 mL, 82 mmol) at 0 0C. Morpholine (5.6 g, 68 mmol) was added slowly at O0C. The reaction was slowly warmed up to room temperature and stirred overnight. LC and LCMS indicated that a mixture (7: 1) of 2,4- dimorpholino-6-chloropyrimidine 2 and 4,6-dimorpholino-2-chloropyrimidine 1 were formed. Formation of 2,6-dichloro-4-morpholinopyrimidine 3 was also observed. Water (700 mL) was added to the reaction mixture was and the resulting precipitate was filtered to give 7 g of the mixture described above. The crude material was purified by silica gel chromatography (3%-20% EtOAc-DCM) yielding 4,6-dimorpholino-2-chloropyrimidine
