Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 78686-79-0, name is Methyl 5-bromo-2-chloronicotinate. This compound has unique chemical properties. The synthetic route is as follows. Recommanded Product: Methyl 5-bromo-2-chloronicotinate

Compound WX069-1 (7.00 g, 27.95 nmol) wasdissolved in dimethyl sulfoxide solution (50.00 mE) at roomtemperature, followed by the addition of cesium fluoride(8.00 g, 52.67 mmol) at room temperature. The reactionmixture was heated to 550 C. and stirred for 14 hours. Afterthe reaction, the mixture was cooled to room temperature,quenched with saturated brine (10 mE), diluted with water(50 mE) and extracted with ethyl acetate (20 mLx3). Thecolunm c1omatography (eluent: petroleum ether/ethylorganic phases were separated, washed with water (50mEx2) and dried over anhydrous sodium sulfate, followedby filtration. The filtrate was concentrated under reducedpressure. The obtained residue was isolated by silica gelacetate1 00/1 – 100/15, volume ratio) to obtain the targetproduct WX069-2. ?H NMR (400 MHz, CDC13) oe: 8.64-8.31 (m, 2H), 3.98 (s, 3H).
