The desired product was prepared using a procedure similar to step 2 of example 3. Thus, 6-bromo-2,3,4,9-tetrahydro-1H-carbazole (1.501 g, 6 mmol) was reacted with k-t-butoxide (0.707 g, 6.3 mmol) and methyl iodide (0.894 g, 6.3 mmol) in DMF (15 ml) to give the desired product (1.443 g, 5.463 mmol, 91%) as an off-white solid, mp 70-73° C. 1H NMR (DMSO-d6) δ 1.73-1.77 (m, 2H), 1.82-1.87 (m, 2H), 2.58 (t, J=6.1 Hz, 2H), 2.70 (t, J=6.1 Hz, 2H), 3.58 (s, 3H), 7.13 (dd, J=1.7, 8.6 Hz, 1H), 7.32 (d, J=8.6 Hz, 1H), 7.55 (d, J=1.5 Hz, 1H); [EI], m/z 263/265 (M)+.
