Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 1260243-04-6, name is Ethyl 5-amino-1H-pyrazole-4-carboxylate, A new synthetic method of this compound is introduced below., category: pyrazoles-derivatives<\/a><\/p>\n

Step 3: preparation of ethyl 5-acetamido-1 H-pyrazole-4-carboxylate. A mixture of ethyl 5-amino-1H-pyrazole-4-carboxylate (100 g, 0.65 mol) and acetyl chloride (441.2 g, 5.62 mol) at 0C was heated to reflux for 4h. The reaction was concentrated in vacuo to remove excess acetyl chloride. Water (1.0 L) was added and the mixture was stirred for 16 h, after which it was filtered to afford the title compound as an off white solid (120g, 94%). MS (M+H) m\/z 198. 1H NMR (400 MHz, CDCI3) 6 ppm: 9.57(1 H, s), 7.75 (1H, s), 4.33-4.28 (2H, q, J = 7.08), 2.27 (3H, s), 1 .37-1.34 (3H, s).<\/p>\n
