Versuchsvorschrift
To a stirred solution of 2-methylquinoline-6-carbaldehyde (1.00 g, 5.8 mmol) in THF (60 mL) in a 100 mL round-bottomed flask equipped with a magnetic stirrer was added NaBH4 (0.221 g, 5.8 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 (10 mL). After stirring for 15 min at RT, 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 (2-methylquinolin-6-yl)methanol SLA 47080A as a yellow oil (1.056 g, quant.).
