Participants

Reaction Steps

A solution of [6-(3-Guanidino-propoxy)-2-oxo-1,2,3,4-tetrahydro-quinolin-3-yl]-acetic acid ethyl ester (0.76 g, 1.6 mmol) in ethanol (7 mL) was treated with 0.5 N aqueous NaOH and heated at reflux for 3 h. The resulting precipitate was cooled to room temperature, treated with trifluoroacetic acid (1.5 mL) and the solution thus formed concentrated in vacuo to yield a clear, colorless oil. Purification by reverse phase HPLC gave the title compound (0.38 g, 55% yield) as a fluffy white solid.
