Procedure
100 ml of ethanol, 4.8 g (28.2 mmol) of 1-undecanal and 0.8 ml of concentrated hydrochloric acid were added to 5.0 g (18.7 mmol) of N1-(2,3,4-trifluorophenyl)-biguanide hydrochloride, and the mixture was refluxed for 24 hours. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography (elution with a mixture of chloroform and methanol (9:1.5)), and recrystallized from 80% aqueous acetonitrile to obtain 3.2 g of colorless crystals having a melting point of 210 to 213° C.
