Reference of 1235036-15-3 ,Some common heterocyclic compound, 1235036-15-3, molecular formula is C10H11BrClNO2, 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.
To Example 1.1.10 (100 mg) and tert-butyl 3-bromo-6-chloropicolinate (52.5 mg) in dioxane (2 mL) was added tris(dibenzylideneacetone)dipalladium(0) (8.2 mg), K3P04 (114 mg), 1,3,5,7- tetramethyl-8-phenyl-2,4,6-trioxa-8-phosphaadamantane (5.24 mg) and water (0.8 mL). The mixture was stirred at 95 C for 4 hours, diluted with ethyl acetate and washed with water and brine. The organic layer was dried over Na2S04, filtered, concentrated and purified by flash chromatography, eluting with 20% ethyl acetate in heptanes and then with 5% methanol in dichloromethane, to provide the title compound. MS (ESI) m/e 643.3 (M+H)+.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1235036-15-3, its application will become more common.
