Reaction Steps

To a suspension of 5-morpholin-4-yl-3-oxo-2-(phenylhydrazono)pentanenitrile (1.2 mmole) in 15 mL of diethyl ether was slowly added a solution of hydrazine hydrate (2.4 mmol) in 2 of THF which resulted in a clear red solution. After 2 hours, another portion of hydrazine (2.4 mmol) was added at which point some yellow precipitate was observed. The reaction was stirred at ambient temperature overnight. The solid was collected by filtration, purified by recrystalization from ethanol and dried in vacuo to yield 150 mg (41%) of the title compound. MS (m/z, ES+): 301 (M+1, 100%). 1H NMR (ppm, 300 MHz, DMSO-d6) δ 11.63 (br s, 1H), 7.67 (m, 2H), 7.44 (m, 2H), 7.29 (m, 1H), 6.97 (br s, 2H), 3.55 (m, 4H), 2.93 (m, 2H), 2.66 (m, 2H), 2.43 (m, 4H).
