Application of 99368-68-0 ,Some common heterocyclic compound, 99368-68-0, molecular formula is C6H4ClF3N2, 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.
B. To compound 27a (0.241 g, 1.23 mmol) in 4 mL CH3CN was added iPr2NEt (0.24 mL, 1.38 mmol) and compound 20b (0.24 mL, 1.32 mmol). After 18 hours the reaction was evaporated in vacuo, taken up in 25 mL EtOAc and washed successively with 25 mL saturated NaHCO3 then 25 mL brine. The organic phase was dried over Na2SO4, filtered, and evaporated in vacuo to a residue. The residue was purified via silica gel chromatography (30-60% EtOAc/heptane) to give compound 27b as a yellow-tan powder. MS: M+H+=397.0, 1H NMR (d6-DMSO): delta 10.67 (s, 1H), 8.80 (s, 1H), 8.59 (s, 1H), 7.69 (d, 2H), 7.51 (d, 2H), 3.02 (t, 2H), 2.78 (t, 2H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,99368-68-0, its application will become more common.
