Acetate → Isoamyl Acetate

참여 물질

반응 단계

1-Butanol, 3 methyl, acetate. Under an atmosphere of argon, acetyl chloride (6.5 ml, 91.8 mmol) was added dropwise to a 0° C. solution of isoamyl alcohol (5 ml, 45.9 mmol), N,N-dimethylpyridine (2.8 g, 23 mmol), and anhydrous pyridine (4.1 ml, 50.5 mol) in dichloromethane (92 ml). The reaction mixture was poured into 100 ml of 0.1 N HCl, and the resulting layers were separated. The organic layer was washed with 50 ml of saturated aqueous ammonium chloride then dried over magnesium sulfate. The organic layer was filtered and concentrated in vacuo to a clear oil. The resulting oil was purified by distillation (bp 134-136° C.) to give isoamyl acetate. 1H NMR (300 MHz, CDCl3) 4.08 (t, 2H, J 6.9), 2.03 (s, 3H), 1.68 (m, 1H), 1.51 (q, 2H, J 6.9), 0.92 (d, 6H, J 6.6).
