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. 1572-10-7, name is 3-Amino-5-phenylpyrazole, A new synthetic method of this compound is introduced below., SDS of cas: 1572-10-7<\/a><\/p>\n

General procedure: The compound tetronic acid (15) (80 mg, 0.8 mmol) was dissolved in 4 mL of ethanol, followed by addition of terphenyl aldehyde 13a (221.2 mg, 0.8 mmol) and 3-amino-5-phenyl pyrazole 14a (127.2 mg, 0.8 mmol). The reaction mixture was refluxed in ethanol at 78 C for an hour. Then reaction suspension was cooled to room temperature, and the precipitated product was collected by vacuum filtration and washed with ethanol (3 mL), then recrystallized from ethanol to afford pure compound 8a as a white solid, 340 mg in 85% yield. Mp: 273-274 C; 1H NMR (300 MHz, DMSO-d6): delta 4.80 (s, 2H), 5.25 (s, 1H ), 6.89-6.99 (m, 1H), 7.19-7.35 (m, 7H), 7.42-7.52 (m, 4H), 7.65 (dd, 4H, J = 8.8, 11.7 Hz), 8.05 (s, 1H), 10.19 (s, 1H ), 12.56 (s, 1H); 13C NMR (300 MHz, DMSO-d6): delta 30.5, 64.8, 94.4, 99.8, 111.1, 111.3, 113.2, 121.3, 125.4, 126.1, 126.7, 126.9, 127.1, 127.2, 127.3, 128.3, 128.7, 128.8, 132.7, 137, 137.2, 138.8, 139.3, 145.8, 152.7, 157.7, 172.2; MS (ESI): 500 [M+H]+; HRMS (ESI) calcd for C32H23O2N3F [M+H]+ 500.1712; found: 500.1738.<\/p>\n

The synthetic route of 1572-10-7 has been constantly updated, and we look forward to future research findings.<\/p>\n
