実験手順
This was prepared by the method of Example 1(a) from the product of step (c) (1.2/1 mixture, w/w) and 4-fluorophenylboronic acid. The crude product was purified on silica gel, eluting initially with hexane/EtOAc (4/1, v/v) followed by EtOAc. The title compound (63% based on the compound of step (c)) was obtained as a white foam. Rf 0.18 (EtOAc). MS m/z 511 (MH+). 1H NMR (CDCl3) δ: 2.00 (2H, m), 3.14 (4H, m), 3.35 (2H, m),3.48 (3H, s), 3.55 (2H, m), 3.66 (4H, m), 3.84 (2H, m), 3.94 (2H, m), 3.97 (3H, s), 4.52 (2H, bs), 6.90 (1H, bs), 7.16 (2H, m), 7.32 (2H, m). Found: C,60.91; H,6.32; N,15.73; C26H31N6O4F 0.2.EtOAc requires C,60.90; H,6.17; N,15.91%.
