5-BENZYL-1H-PYRAZOL-3-AMINE Use and Manufacturing

A solution of 3-oxo-4-phenyl butyronitrile (Method 26; 0.58 g, 3.64 mmol) and hydrazine monohydrate (0.177 ml, 3.64 mmol) in EtOH(16ml) was heated to reflux for 3 hours. After cooling to25 C, the reaction was concentrated under reduced pressure, extracted with DCM (15 ml), and washed twice with brine. The organic layer was dried over anhydrousNa2S04 and concentrated to give an orange solid. The resulted solid was triturated with hexanes : ether (1: 1) solution and collected by filtration to afford the title compound as a yellow solid (0.38 g, 60percent). 1H NMR (400 MHz, CDC13) 5 3.9 (s, 2 H), 4.89 (br s, 1 H), 5.44 (s, 1 H), 7.19-7. 34(m, 5H). MS: Calcd. : 173; Found: [M+H]+ 174.A solution of 3-oxo-4-phenyl butyronitrile (Method 26; 0.58 g, 3.64 mmol) and hydrazine monohydrate (0.177 ml, 3.64 mmol) in EtOH(16ml) was heated to reflux for 3 hours.
