실험 절차

Using a procedure analogous to that used to prepare 30B, 61A (5 g, 23 mmol) was heated in a pressure vessel with 9-BBN at 100° C. for 10 h and worked up as in 30B to yield 61B (2.9 g, 54%) as an oil. 1H NMR (400 MHz, CDCl3) δ ppm 2.95 (t, J=6.59 Hz, 2 H) 3.85 (t, J=6.59 Hz, 2 H) 7.14 (d, J=7.91 Hz, 1 H) 7.33 (dd, J=8.13, 1.98 Hz, 1 H) 7.52 (d, J=2.20 Hz, 1 H).
