Electric Literature of 175137-46-9<\/a>,Some common heterocyclic compound, 175137-46-9, name is 5-Cyclopropyl-1H-pyrazol-3-amine, molecular formula is C6H9N3, 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 flask was added Pd(OAc)2 (22.4 mg, 0.1 mmol), (biphenyl-2- ylmethylene)bis(dimethylphosphine) (60 mg, 0.2 mmol) and sodium tert-butoxide (240 mg, 2.5 mmol). The flask was sealed and refilled with N2. To the mixture was added a solution of EPO 6-bromo-N-(4-fluorobenzyl)pyridin-2-amine (Method 19; 281 mg, 1.0 mmol) and 5- cyclopropyl-lH-pyrazol-3 -amine (123 mg, 1.0 mmol) in toluene (5 ml). The reaction mixture was heated at 110C overnight. The solvent was removed and EtOAc was added and the mixture was washed with brine and was concentrated. Semi-prep HPLC (Gilson) purification gave the title compound (6.4 mg, 2%). 1H NMR (CDCl3) delta 0.65 (m, 2H), 0.95 (m, 2H), 1.80 (m, IH), 4.43 (m, 2H), 4.91 (br s, IH), 5.60 (br s, IH), 5.80 (m, IH), 6.18 (m, IH), 6.73 (m, IH), 7.00 (m, 2H), 7.25 (m, 3H).<\/p>\n

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 5-Cyclopropyl-1H-pyrazol-3-amine, its application will become more common.<\/p>\n","protected":false},"excerpt":{"rendered":"
