Following a procedure analogous to that described above for 49a, but substituting 4-biphenylcarbonyl chloride for benzoyl chloride, the title compound was obtained as a white solid in 41% yield: 1H NMR (300 MHz, CDCl3) δ 8.01 (d, J=7.2 Hz, 2H), 7.39-7.69 (m, 7H), 4.12 (q, J=6.9 Hz, 2H), 2.99 (t, J=7.2 Hz, 2H), 2.30(t, J=7.5 Hz, 2H), 1.76 (m, 2H), 1.65 (m, 2H), 1.40 (m, 4H), 1.25 (t, J=7.2 Hz, 3H).
