Diethylamine → 1-(3-Chlorophenyl)-3-(diethylaminomethylene)-2(1H,3H)-indolone

Participants

Reaction Steps

1-(3-Chlorophenyl)-3-(ethoxymethylene)-2(1H,3H)-indolone (0.15 g, 0.5 mmole), diethylamine (5 ml, 48 mmole) and ethanol (30 ml) were combined and stirred 24 hours at 25°. The reaction mixture was concentrated in vacuo to an oil. The oil was taken up in ethyl acetate, washed with H2O and then brine, dried over MgSO4 and evaporated to yield title product which crystallized on cooling and trituration with ether/pentane, 96 mg. m.p. 74°-75.5°.
