Versuchsvorschrift

Bromomethyl-(6-methoxy-[1,5]-naphthyridin-4-yl)-ketone (6.6 g, 0.023 mol) in toluene was treated with (+)-B-chlorodiisopinocamphenylborane ((+)-DIP-chloride) (12 g, 0.037 mol) and stirred overnight, then diethanolamine (15 g, 0.14 mol) added and the mixture stirred for 3 hours, filtered and evaporated. Chromatography on silica gel (ethyl acetate-hexane) gave a white solid (4.73 g, 73%).
