反応手順
4-(N,N-Diphenylamino)benzyl alcohol (5.94 g, 0.0216 mol), pyridine (16 mL) and acetic anhydride (11.4 mL) were mixed in a three-neck flask equipped with a condenser and addition funnel. The resulting mixture was stirred overnight at room temperature. Deionized water (50 mL) was then added and the resulting mixture stirred for 2 hours. The product was obtained by filtration, and recrystallized from hexane to yield the desired product (6.52 g, 95%). m.p. 105-6° C.; 1H NMR δ: 2.10 (s, 3H, CH3), 5.04 (s, 2H, CH2), 7.0-7.4 (m, 14H, phenyl). Analysis: Calculated for C19H17NO2: C, 79.46%; H, 6.03%; N, 4.41%. Found: C, 79.37 %; H, 5.72 %; N, 4.41%.
