Procedure
Using a procedure analogous to that used to prepare 30B, 36A (1.98 g, 5.1 mmol) was heated in a pressure vessel with 9-BBN at 100° C. for 15 h to yield 36B (0.95 g, 81%) as a clear oil. 1H NMR (400 MHz, CDCl3) δ ppm 1.23 (t, J=7.58 Hz, 3 H) 2.66 (q, J=7.58 Hz, 2 H) 2.87 (t, J=6.82 Hz, 2 H) 3.83 (t, J=6.82 Hz, 2 H) 7.06 (d, J=8.08 Hz, 1 H) 7.25-7.31 (m, 1 H) 7.32-7.37 (m, 1 H).
