Related Products of 1082745-50-3<\/a>, These common heterocyclic compound, 1082745-50-3, name is 5-Amino-1-(tetrahydro-2H-pyran-4-yl)-1H-pyrazole-4-carboxamide, 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 suspension of 0.132 g (0.63mmol) of 5-amino-l-(tetrahydro-pyran-4-yl)-l-H-pyrazole-4- carboxylic acid amide (see PCT patent application WO2010\/026214) in dry EtOH (1.5mL), 0.066 g (1.66 mmol) of sodium hydride (60 % suspension in mineral oil) were added at room temperature under nitrogen. After lOmin, 0.181mg (0.945mmol) of Example 13 A were added and the reaction mixture was heated to 140C for 40 min in a microwave oven (Power 100W). The reaction mixture was then diluted with DCM, water was added, organics separated and dried over sodiumsulphate. Organics were evaporated under reduced pressure and the crude purified by flash cromatography (DCM\/IPA 98:2) to obtain the title compound as a white solid. (54mg, 32%).HPLC-MS (Method lEh): R, = 8.01 minMS (APCI pos): m\/z = 352 (M+H)+<\/p>\n

Statistics shows that 5-Amino-1-(tetrahydro-2H-pyran-4-yl)-1H-pyrazole-4-carboxamide is playing an increasingly important role. we look forward to future research findings about 1082745-50-3.<\/p>\n
