Participants

Reaction Steps

150 ml of methanol, 120 ml of acetone and 0.5 ml of concentrated hydrochloric acid were added to 7.0 g (18.6 mmol) of N1-(3-quinolyl)-N5-octyl-biguanide dihydrochloride. The mixture was refluxed for 26 hours, and 1.8 ml of concentrated hydrochloric acid was further added thereto. The mixture was refluxed for 22 hours, and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (elution with a mixture of chloroform and methanol (9:1)) to obtain 5.3 g of a pale yellow powder.
