Versuchsvorschrift

NaBH4 (138 mg, 3.6 mmol) was added to a solution of 5-(4-fluorophenyl)-1,3-oxazole-2-carbaldehyde (0.58 g, 3.03 mmol) in methanol (10 ml). The mixture was stirred at room temperature for 2 hours, then poured into water (50 ml), extracted with DCM (30 ml), washed with brine (20 ml), dried over MgSO4 and concentrated in vacuo to afford 460 mg (79%) of the title compound: δH (360 MHz, CDCl3) 2.57 (1H, m), 4.79 (2H, d, J 5.5) 7.12 (2H, t, J 8.5), 7.24 (1H, s), 7.60-7.64 (2H, m); m/z (ES+) 194 (MH+).
