Electric Literature of 31230-17-8<\/a>, A common heterocyclic compound, 31230-17-8, name is 5-Methyl-1H-pyrazol-3-amine, molecular formula is C4H7N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.<\/p>\n

To a solution of compound 12 (84 mg, 0.30 mmol) in DMF (3 mL) at room temperature were added DIPEA (0.103 mL, 0.6 mmol) and 5-methyl-1H-pyrazol-3-amine (88 mg, 0.9 mmol).The reaction mixture was heated at 40\u00b0 C. overnight.Water was added, and the yellow precipitate was collected by filtration and washed with water.The solid was purified by silica gel chromatography eluting with DCM\/MeOH to give compound I (30 mg, 29percent).1H NMR (300 MHz, DMSO-d6) delta 2.19 (s, 3H), 6.54 (s, 1H), 7.40 (m, 2H), 7.68 (t, 1H), 7.9-7.7 (m, 2H), 8.08 (m, 2H), 8.74 (d, 1H), 10.66 (s, 1H), 12.20 (s, 1H); LC-MS (ESI) m\/z: 348 (M+H)+.<\/p>\n

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.<\/p>\n
