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 (1, 500 mg, 6%); 2,4 -dimorpholino-6-chloropyrimidine (2, 4.6 g, 59%) and 2,6-dichloro- 4-morpholinopyrimidine (3, 1.5 g, 24%).[0235] 4,6-dimorpholino-2-chloropyrimidine 1: LCMS (m/z): 284.8 (MH+); 1H NMR (CDCl3): delta 5.4 (s, IH), 3.76 (q, 8H), 3.55 (q, 8H). [0236] 2,4-dimorpholino-6-chloropyrimidine 2: LCMS (m/z): 284.8 (MH+); 1UNMR (CDCl3): delta 5.88 (s, IH), 3.74 (m, 12H), 3.55 (q, 4H).[0237] 2,4-dicholoro-6-morpholinopyrimidine 3: LCMS (m/z): 233.8 (MH+); 1H NMR (CDCl3): delta 6.4 (s, IH), 3.77 (m, 4H), 3.65 (bs, 4H).

According to the analysis of related databases, 3764-01-0, the application of this compound in the production field has become more and more popular.
