実験手順
To benzofuran-2-carbaldehyde (4 g, 27.4 mmol, 1 eq.), THF (50 mL) and methanol (50 mL) were added, under argon, and the reaction was cooled using an ice-salt bath. Then sodium borohydride (3.11 g, 82.1 mmol, 3 eq.) was added in several portions, and the reaction was allowed to warm slowly to room temperature for 1 hour. After work-up, benzofuran-2-yl-methanol was obtained in quantitative yield. 1H NMR (400 MHz, DMSO-d6) δ ppm 4.6 (d, J=5.8 Hz, 2 H) 5.5 (t, J=5.9 Hz, 1 H) 6.8 (s, 1 H) 7.3 (m, 2 H) 7.6 (m, 2 H).
