Reference of 83-10-3<\/a>, The chemical industry reduces the impact on the environment during synthesis 83-10-3, name is 1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxylic acid, I believe this compound will play a more active role in future production and life.<\/p>\n

Step 2) 4-(3-chloro-4-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxamido)phenoxy)picolinamide To a suspension of 4-(4-amino-3-chlorophenoxy)picolinamide (191 mg, 0.72 mmol) and 1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxylic acid (168 mg, 0.72 mmol) in DCM (10 mL) was added EDCI (166 mg, 0.86 mmol) and HOAT (20 mg, 0.14 mmol). The reaction was stirred at 46 C. for 6 hours, followed by the addition of 1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxylic acid (32 mg, 0.14 mmol) and EDCI (27 mg, 0.14 mmol). The mixture was further stirred at 46 C. for 13 hours, then cooled to rt and diluted with water (10 mL). The resulted mixture was extracted with ethyl acetate (10 mL*3), and the combined organic phases were washed with brine (10 mL), dried over anhydrous Na2SO4, and concentrated in vacuo. The residue was purified by a silica gel column chromatography (DCM\/MeOH (v\/v)=50\/1) to give the title compound as a pale yellow solid (160 mg, 46.5%). MS (ESI, pos. ion) m\/z: 478.2 [M+H]+; 1H NMR (400 MHz, DMSO-d6): delta (ppm) 2.71 (s, 3H), 3.37 (s, 3H), 7.19 (m, 1H), 7.23 (m, 1H), 7.43 (m, 3H), 7.50 (m, 2H), 7.60 (m, 2H), 7.72 (s, 1H), 8.13 (s,1H), 8.52 (d, J=5.6 Hz, 1H), 8.63 (d, J=9.1 Hz, 1H), 11.19 (s, 1H).<\/p>\n

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxylic acid, other downstream synthetic routes, hurry up and to see.<\/p>\n
