Reference of 1260243-04-6<\/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. 1260243-04-6 name is Ethyl 5-amino-1H-pyrazole-4-carboxylate, 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

A mixture of ethyl 5-amino-1H-pyrazole-4-carboxylate (546 mg, 3.52 mmol) and 5,5- dimethylhexane-2,4-dione (1 .03 g, 97 % purity, 7.03 mmol) in acetic acid (2.7 ml) was heated for 1 h at 11 OC in a microwave reactor (Biotage In itator). Upon cooling to room temperature, the reaction mixture was portioned between water and dichlormethane and the organic phase was washed with water, filtrated through a silicone filter and concentrated undervacuum. The crude product was purified by flash chromatography (25 g Snap Cartrigde, hexanes\/ethyl acetate gradient) to yield the title compound (850 mg, 93% yield). LC-MS (Method 1): R = 1 .25 mm; MS (ESipos) m\/z = 262.2 [M+H].1H-NMR (400 MHz, DMSO-d6) delta [ppm]: 1.281 (2.05), 1.299 (4.51), 1.316 (2.11), 1.375(0.78), 1.558 (16.00), 2.619 (8.39), 4.252 (0.66), 4.270 (2.08), 4.288 (2.05), 4.305 (0.61),7.072 (2.38), 8.569 (2.97).<\/p>\n
