Versuchsvorschrift
1-(5-Fluoropyrimidin-2-yl)ethanone (Method 75, 0.77 g) was dissolved in MeOH (15 ml), and the solution was cooled to 0° C. NaBH4 (0.210 g, 5.55 mmol) was added. The mixture was stirred at room temperature for 1 hour and then partitioned between EtOAc and H2O. The organic extract was washed with brine, dried (Na2SO4), filtered, and concentrated to give the title compound as a yellowish oil (0.79 g, 99%). 1H NMR (CDCl3) δ 8.65 (s, 2H), 5.20 (m, 1H), 4.00 (br s, 1H), 1.80 (d, 3H).
