Versuchsvorschrift
NaBH4 (0.0788 g, 2.08 mmol) was dissolved in 3.2 mL MeOH(H2-formation). At 0° C. a solution of 3,5-difluoropyridine-4-carbaldehyde (0.200 g, 1.40 mmol) in 0.8 mL MeOH was added dropwise (H2-formation). The reaction mixture was stirred 5 h at rt. Water was added dropwise and the mixture was extracted 3 times with EtOAc. The combined organic phases were washed with brine. The organic phase was dried with Na2SO4, filtrated and the filtrate evaporated. The desired product was obtained as a white solid (203 mg),
