Electric Literature of 1082745-50-3<\/a>,Some common heterocyclic compound, 1082745-50-3, name is 5-Amino-1-(tetrahydro-2H-pyran-4-yl)-1H-pyrazole-4-carboxamide, molecular formula is C9H14N4O2, 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 0.8 g (3.805 mmol) of 5-amino-l-(tetrahydro-pyran-4-yl)-l-H-pyrazole-4- carboxylic acid amide (see PCT patent application WO2010\/026214) in 8 mL anhydrous EtOH , 0.457 g (19.6 mmol) of sodium hydride (60 % suspension in mineral oil) were added at room temperature under nitrogen. After 1 h under stirring, 1.2g (11.42mmol) of trans- cyclobutane-l,2-dicarbonitrile were added and the reaction mixture was heated to 140C for 45 min in a microwave oven. The solvent was removed under reduced pressure. The residue was dissolved in DCM, water was added and phases were separated. Organic layers were dried over sodium sulphate and evaporated under reduced pressure. The crude was purified by flash cromatography (Cy\/EtOAc from 80\/20 to 100%) to obtain the title compound as yellow solid. (0.64g, 55%)HPLC-MS(MethodlEh):R,=6.21minMS (APCI): m\/z = 300 (M+H)+<\/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-Amino-1-(tetrahydro-2H-pyran-4-yl)-1H-pyrazole-4-carboxamide, its application will become more common.<\/p>\n
