Following a procedure analogous to that described above for 49a, but substituting p-anisoyl chloride for benzoyl chloride, the title compound was obtained as a light yellow solid in 59% yield: 1H NMR (300 MHz, CDCl3) δ 7.94 (d, J=9.0 Hz, 2H), 6.93 (d, J=9.0 Hz, 2H), 4.12 (q, J=6.9 Hz, 2H), 3.87 (s, 3H), 2.91 (t, J=7.2 Hz, 2H), 2.30(t, J=7.5 Hz, 2H), 1.74 (m, 2H), 1.65 (m, 2H), 1.39 (m, 4H), 1.25 (t, J=6.9 Hz, 3H); 13C NMR (75.4 MHz, CDCl3) δ 14.19, 24.29, 24.75, 28.91, 28.96, 34.21, 38.06, 55.37, 60.10, 113.58, 130.02, 130.21, 163.23, 173.71, 198.93.
