Electric Literature of 35277-02-2<\/a>, 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. 35277-02-2, name is 4-Fluoro-1H-pyrazole, This compound has unique chemical properties. The synthetic route is as follows.<\/p>\n

To a solution of 2-ch loro-N-(2 ,4-d imethoxybenzyl )-5-nitrobenzenesulfonam ide (5.00 g, 11.6 mmol) in acetonitrile (135 mL) were added 4-fluoro-1H-pyrazole (1.50 g, 17.4 mmol) and powdered potassium carbonate (4.82 g, 34.9 mmol) and it was stirred overnight at10000. The reaction mixture was concentrated in vacuo and the residue was extracted with dichioromethane and water. The organic phase was washed with brine and dried over sodium sulfate. Concentration in vacuo led to the crude title compound (5.54 g, quant., app. 85 % purity) that was used without further purification in the next step.LC-MS (Method A): Rt = 1.23 mm; MS (ESIpos): mlz = 437 [M+H]1HNMR (400MHz, DMSO-d6) oe [ppm]: 3.48 (s, 3H), 3.62 (s, 3H), 4.13 (s, 2H), 6.15 (d,1H), 6.28 (dd, 1H), 7.09 (d, 1H), 7.81 (d, 1H), 8.00-8.10 (m, 2H), 8.23 (d, 1H), 8.43 (dd,H), 8.59 (s, 1 H).<\/p>\n
