In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 17635-45-9 as follows. Safety of 4-Pyrazol-1-yl-phenylamine<\/a><\/p>\n

General procedure: A mixture of aniline derivative 1a?1e (1 mmol) and 1 cm3concentrated hydrochloric acid was thoroughly stirred atroom temperature for 15 min and then cooled to 0 C. Asolution containing 0.069 g sodium nitrite (1 mmol) in 10 cm3 water was added dropwise to the initial mixtureduring 40 min. An aqueous solution of aromatic nucleophile(1 mmol) in NaOH 10percent (5 cm3) was then addedand the resulted mixture was stirred for 1 h at 0 C. Theprecipitated solid was filtered, washed with water and dried in air. The products 2a?2c, 2e, 2f, 2m, and 2o were purifiedby recrystallization in ethanol, but preparative TLC (nhexane?EtOAc, 4:1) was applied for purification of products2d, 2g?2l, 2n, and 2p.<\/p>\n
