Related Products of 17635-45-9<\/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. 17635-45-9, name is 4-Pyrazol-1-yl-phenylamine, This compound has unique chemical properties. The synthetic route is as follows.<\/p>\n

EXAMPLE 25 1-Isopropyl-7-[4-(pyrazol-1-yl)phenylamino]-3,4-dihydro-pyrimido[4,5-d]pyrimidin-2(1H)-one; Compound With Trifluoroacetic Acid Prepared from 200 mg (0.79 mmol) of 1-isopropyl-7-methanesulfinyl-3,4-dihydro-pyrimido[4,5-d]pyrimidin-2(1H)-one, 250 mg (1.57 mmol) of 1-(4-aminophenyl)pyrazole and 182 muL (2.36 mmol) of trifluoroacetic acid in 3.2 mL of acetonitrile. After heating the reaction mixture overnight, a heavy precipitate forms. The cooled reaction mixture is diluted with ethyl acetate and filtered. The solids are washed with ethyl acetate and dried to give 315 mg (86percent) of the trifluoroacetate salt of the title compound: mp 249-252\u00b0 C. (dec). Analysis calculated for C18H19N7O.C2HF3O2: C, 51.84; H, 4.35; N, 21.16. Found: C, 51.94; H, 4.37; N, 21.02.<\/p>\n

The chemical industry reduces the impact on the environment during synthesis 4-Pyrazol-1-yl-phenylamine. I believe this compound will play a more active role in future production and life.<\/p>\n
