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. 63558-65-6, name is 4-Chloro-5-iodopyrimidine, molecular formula is C4H2ClIN2, 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. category: pyrimidines
To a stirred solution of 4-chloro-5-iodopyrimidine (300 mg, 1.248 mmol) in DMF (2 mL) was added cesium carbonate (813 mg, 2.496 mmol) and morpholine (0.435 mL, 4.99 mmol). The reaction was purged with N2, heated to 90 C for 12 hours and then concentrated to give the crude Intermediate 44, which was used directly in subsequent reaction. MS (ES): m/z = 292.1 [M+H]+. ‘H NMR (400 MHz, MeOD) delta ppm 8.69 (1 H, s), 8.56 (1 H, s), 3.76-3.86 (5 H, m), 3.61-3.71 (5 H, m). Intermediate 44 was used in the synthesis of Example 224.
With the rapid development of chemical substances, we look forward to future research findings about 63558-65-6.
