Application of 29274-24-6 ,Some common heterocyclic compound, 29274-24-6, molecular formula is C6H4ClN3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
N-Iodosuccinimide (1.61 g, 7.16 mmol) was added to a solutionof 5-chloropyrazolo[1,5-a]pyrimidine (7) (1 g, 6.51 mmol) in anhydrousDMF (10 mL). After stirring at RT for 4 h the reaction was poured into 10% sodium thiosulfate (75 mL). The resulting precipitate was isolated via filtration and dried (Whatman PS1 filterpaper) to give 19 as a pale brown solid (1.62 g, 89%). 1H NMR deltaH (d6-DMSO, 300 MHz), 9.19 (d, J 7.2, 1H), 8.38 (s, 1H), 7.18 (d, J7.2, 1H). LC-MS tR 6.37 min; LC254 99%; m/z 280.1/282.0 [M+H].This was used without further purification.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,29274-24-6, its application will become more common.
