실험 절차

4-(4-Fluorophenyl)-butyramide (Int. A4) (2.63 g) was dissolved in trifluoroacetic anhydride (10 ml) and stirred for 2 h. The solution was concentrated and then dissolved in dichloromethane and washed with 2N sodium hydroxide solution. The organics extracts were isolated, dried (MgSO4) and concentrated to yield the product (2.3 g, 100%) which contained ˜5% starting amide as an impurity. 1H-NMR (CDCl3) δ 1.96 (2H, app q), 2.31 (2H, t), 2.75 (2H, t), 6.98 (2H, m), 7.14 (2H, m). MS (APCI+) M+1=164, C10H10FN requires 163.
