Participants

Reaction Steps

The desired product was prepared using a procedure similar to step 4 of example 3. Thus, 1-benzyl-6-(4-methoxy-phenyl)-3-methyl-2-phenyl-1H-indole (1.017 g, 2.861 mmol) was reacted with BBr3 (3.4 ml of a 1M solution in CH2Cl2) to give the product (0.726 g, 1.864 mmol, 65%) as a white solid, mp 141-143° C. 1H NMR (DMSO-d6) δ 2.23 (s, 3H), 5.37 (s, 2H), 6.80 (d, J=8.6 Hz, 2H), 6.85 (d, J=7.2 Hz, 2H), 7.13 (t, J=7.3 Hz, 1H), 7.18 (t, J=7.0 Hz, 2H), 7.30 (dd, J=1.5, 8.3 Hz, 1H), 7.38-7.49 (m, 7H), 7.51 (d, J=0.9 Hz, 1H), 7.58 (d, J=8.1 Hz, 1H), 9.40 (s, 1H); IR (solid) 3300, 3030, 1600, 1520, 1450, 1350, 1260, 1230 and 1180 m−1; [ESI(+)], m/z 390 (M+H)+; Anal. Calcd. for C28H23NO: C, 86.34; H, 5.95; N, 3.60; Found: C, 85.88; H, 6.21; N, 3.36.
