3-(1H-indol-3-yl)propanehydrazide

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 3-(1H-Indol-3-yl)-propionic acid hydrazide (0.300 g, 1 eq) and 4-fluorobenzaldehyde (0.183 g, 1 eq) in toluene (7 ml) is refluxed overnight and then evaporated to dryness, to afford 0.450 g of white product that is purified by flash chromatography using neutral alumina and eluting with 1% methanol in chloroform (0.269 g, 59% yield). evaporated to dryness

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 3-(1H-Indol-3-yl)-propionic acid ethyl ester (4.30 g, 1 eq) and hydrazine hydrate (˜9.6 ml, 10 eq) in ethanol (70 ml) is heated at 60° C. overnight. The reaction mixture is concentrated under reduced pressure and diluted with methylene chloride. The new organic solution is washed with water, dried over MgSO4, filtered and evaporated to dryness, to afford the title compound as white solid (3.9 g, 98% yield), which is used as such for the next step. The reaction mixture is concentrated under reduced pressure diluted with methylene chloride The new organic solution is washed with water dried over MgSO4 filtered evaporated to dryness
