Compound 53 was prepared using the synthetic sequence in a manner analogous to the method described for the conversion of compound 12 to compound 16 and illustrated in Scheme 1b. 1H NMR (400 MHz, CDCl3): δ 11.56 (s, 1H), 7.76 (d, J=7 Hz, 1H), 7.60 (d, J=7 Hz, 1H), 7.44 (t, J=7 Hz, 1H), 7.36 (t, J=7 Hz, 1H), 7.07 (d, J=3 Hz, 1H), 6.93 (d, J=3 Hz, 1H), 5.63 (s, 1H), 3.93 (m, 1H), 3.37 (m, 1H), 2.97 (s, 2H), 1.60 (m, 2H), 1.36 (m, 2H), 0.93 (t, J=7 Hz, 3H). MS: m/z (MH+) 362.
