Reaction Steps

The desired product was prepared using a procedure similar to step 4 of example 3. Thus, 3-benzyl-5-(4-methoxy-phenyl)-1-methyl-2-phenyl-1H-indole (0.757 g, 1.876 mmol) was reacted with BBr3 (2.3 ml of a 1M solution in CH2Cl2) to give the product (0.371 g, 0.953 mmol, 51%) as a solid, mp 133-135° C. 1H NMR (DMSO-d6) δ 3.61 (s, 3H), 4.03 (s, 2H), 6.80 (d, J=8.6 Hz, 2H), 7.07-7.10 (m, 3H), 7.18 (t, J=7.9 Hz, 2H), 7.38-7.39 (m, 3H), 7.44-7.55 (m, 7H), 9.36 (s, 1H); IR (solid) 3290, 3020, 1605, 1520, 1480, 1430, 1370, and 1230 cm−1; [ESI(+)], m/z 390 (M+H)+; Anal. Calcd. for C28H23NO-0.25H2O: C, 85.36; H, 6.01; N, 3.55; Found: C, 85.52, H, 5.94; N, 3.32.
