The synthetic route is as follows., COA of Formula: C9H10FNO2

Example 48: 4-tert-Butyl-N-[5-chloro-2-(2-fluoro-benzoyi)-pyridin-3-yl]- benzenesulfonamide; [00439] N-(2-Bromo-5-chloro-pyridin-3-yl)-4-tert-butyl-N-methoxymethyl- benzenesulfonamide (140 mg, 300 mmol) was placed in a dry 2-neck 10 mL round-bottom flask. The flask was evacuated and purged with nitrogen, followed by the addition of THF (1 mL). The homogeneous mixture was lowered to -5 C and /PrMgCI (0.33 mL, 2.0 M) was added dropwise. Upon completion of the addition, the reaction was stirred 90 minutes, followed by the slow addition of 2- fluoro-N-methoxy-N-methyl-benzamide (140 mg, 750 mmol). The reaction was stirred overnight, during which the ice-bath warmed to room temperature. The following day, the reaction was quenched with a small quantity of MeOH and the solvents evaporated in vacuo. The residue was subsequently treated with 4.0 M HCI (in dioxane) (1 mL, 4.0 mmol) and H2O (0.33 mL), and then stirred at 80 C for two hours. The resultant solution was diluted with EtOAc, washed with water, saturated sodium bicarbonate, and brine; dried with MgSO4, and evaporated employing reduced pressure. The crude sulfonamide was finally purified via preparatory TLC (20% EtOAc/hexanes) and recrystallization from MeCN/H2O to afford 98 mg of the title compound: 1H NMR (400 MHz, CDCI3) delta 10.6 (s, 1 H), 8.3 (d, 1H), 8.2 (d, 1H), 7.74 (d, 2H), 7.6 (d, 1 H), 7.5 (d, 1 H), 7.43 (d, 2H), 7.42-7.37 (m, 2H), 1.26 (s, 9H); MS (ES) M+H expect 447.1 , found 447.5.

According to the analysis of related databases, 198967-24-7, the application of this compound in the production field has become more and more popular.

The origin of a common compound about 198967-24-7

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Fluoro-N-methoxy-N-methylbenzamide, its application will become more common.

Reference of 198967-24-7,Some common heterocyclic compound, 198967-24-7, name is 2-Fluoro-N-methoxy-N-methylbenzamide, molecular formula is C9H10FNO2, 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.

A solution of 2-fluoro-N-methoxy-N-methylbenzamide (16 g, 87.4 mmol) in THF (150 mL) was cooled to -78 C. Vinylmagnesium bromide (120 mL, 120 mmol) was slowly added, and the mixture stirred at -78 C. for 10 min, slowly warmed to rt, and stirred for another 3 h. The reaction mixture was quenched with 1 N aq HCl (100 mL) at 0 C. The aqueous layer was extracted with EtOAc (100 mL). The combined organic phase was washed with brine (50 mL), dried over Na2SO4, and concentrated. The residue was purified by column chromatography to afford 1-(2-fluorophenyl)-prop-2-en-1-one (7.6 g, yield: 58.4%) as a colorless oil.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Fluoro-N-methoxy-N-methylbenzamide, its application will become more common.
