Related Products of 28466-26-4<\/a>, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 28466-26-4 name is 4-Aminopyrazole, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.<\/p>\n

General procedure: A mixture of the appropriate aminopyrazole 1 (0.01 mol), NaN3 (0.78 g, 0.012 mol), andtriethyl orthoformate (1.60 ml, 0.015 mol) or triethylorthoacetate (1.74 ml, 0.015 mol) in glacial acetic acid(10 ml) was stirred for 3-4 h at 90. The reaction mixturewas cooled and poured into ice water (50 ml). In the case ofcompounds 2a-c, 4b, the precipitate that formed wasfiltered off, washed with water, and recrystallized from EtOH. In the case of compounds 2d, 3a, 4a,c, the aqueouslayer was extracted with ethyl acetate (3\u00a1\u00c115 ml), and theorganic layer was dried over anhydrous Na2SO4. Thesolvent was removed at reduced pressure, and the solidresidue was recrystallized from EtOH.<\/p>\n
