Reaction Steps

Following general procedure A, a mixture of 3,4,5-trimethoxyphenylmethanesulfonate (131 mg, 0.5 mmol), 4-fluoroaniline (57 μL, 0.6 mmol), K2CO3 (97 mg, 0.7 mmol), 10 (4 mg, 1 mol %), 1 (2.5 mg, 1 mol %), and t-BuOH (6 mL) was heated to 110° C. for 16 h. The crude product was purified via the Biotage SP4 (silica-packed 25+M; 5-40% EtOAc/hexanes) to provide the title compound as a yellow oil (120 mg, 87%). 1H NMR (300 MHz, CDCl3) δ: 6.99 (m, 4H), 6.22 (s, 2H), 5.57 (s, 1H), 3.80 (s, 3H), 3.78 (s, 6H) ppm. 13C NMR (75 MHz, CDCl3) δ: 159.7, 156.5, 154.1, 140.5, 139.6, 132.5, 120.4, 120.3, 116.4, 116.1, 95.2, 61.3, 56.2 ppm. IR (neat, cm−1): 3360, 2937, 1597, 1499, 1454, 1216, 1129, 1007, 785. Anal. Calcd. for C15H16FNO3: C, 64.97; H, 5.82. Found: C, 65.24; H, 6.00.
