Procedure

ethyl 2,7-dichloro-6-methoxy-4-[(4-methyl-1-piperazinyl)methyl]-3-quinolinecarboxylate (6 g, 14.5 mmol) is dissolved in methylene chloride (120 ml). A molar solution of diisobutylaluminium hydride in methylene chloride (60 ml, 60 mmol) is added slowly. Agitation is carried out for one hour at ambient temperature. The reaction mass is slowly poured into 300 ml of a 20% solution of Rochelle salt. Agitation is carried out for one hour, followed by filtering on celite and decanting; the organic phase is washed with a saturated solution of sodium chloride, dried over magnesium sulphate, filtered and evaporated under reduced pressure. The solid is taken up in isopropyl ether, filtered and dried under vacuum. 4.3 g of sought product (80%) is obtained, in the form of a yellow solid.
