Versuchsvorschrift
To a stirred solution of 6-methoxy-2-(propylamino)quinoline-3-carbaldehyde SLA 28172 (1.565 g, 6.41 mmol) in THF (120 mL) in a 250 mL round-bottomed flask equipped with a magnetic stirrer was added sodium borohydride NaBH4 (0.242 g, 6.41 mmol) and the mixture was stirred overnight at RT then cooled in an ice bath before quenching by addition of a 1 N aq. HCl solution (40 mL). After stirring for 15 min at that temperature, the mixture was basified to pH=9 with a 2 N aq. NaOH solution. THF was then removed at 40° C. under vacuum and the solution was extracted with CH2Cl2 (200 mL), washed with brine (20 mL), dried over Na2SO4, filtered, and concentrated under vacuum to give (6-methoxy-2-(propylamino)quinolin-3-yl)methanol SLA 28174 as an orange solid (1.55 g, 98% yield).
