Reference of 50270-27-4 ,Some common heterocyclic compound, 50270-27-4, molecular formula is C5HCl3N2O, 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.
Method H: compound 10 (211 mg, 1.0 mmol) was dissolved in ethanol (5 mL) and stirred at -78 C., to which was slowly added hydrazine hydrate (53 muL, 1.1 mmol), monitored by TLC until complete reaction, to which was added ethyl acetate (50 mL). The system washed with water once, and the organic phase was dried with anhydrous sodium sulfate, filtered, concentrated and separated by silica gel column chromatography to obtain compound 11a (127 mg, 67% yield). MS (ESI) m/z: 190 [M+H].
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 50270-27-4, 2,4,6-Trichloropyrimidine-5-carbaldehyde, other downstream synthetic routes, hurry up and to see.
