실험 절차
Phenoxy-2-propanone (3.4 mL, 25 mmol) was dissolved in ethanol (30 mL) and cooled to 0° C. Sodium borohydride (0.95 g; 25 mmol; 1 equiv.) was added. The mixture was stirred and allowed to warm to room temperature overnight. All of the starting material was gone according to tlc analysis, so the mixture was poured into water (30 mL) and ether (30 mL). The layers were separated and the aqueous layer was extracted with ether (2×20 mL). The organic layers were combined and concentrated. The resulting aqueous residue was poured into ether (25 mL). The organic layer was removed, dried (MgSO4), and concentrated to provide 1e (3.2 g; 85%). 1H nmr (300 MHz, CDCl3): 7.332-7.261 (3H, m); 6.995-6.904 (2H, m); 4.15-4.24 (1H, m); 3.972-3.768 (2H, m); 1.559 (1H, s); 1.290 (3H, d, J=6.38 Hz). IR (neat film, cm-1): 3350 (b, s); 2900 (s); 1590 (m). EIMS (m/e): 152 (M+).
