Participants

Reaction Steps

1,1,2-Trimethyl-3-phenyl-1H-benzo[e]indolium perchlorate (11) (0.386 g) was suspended in 50 ml of benzene or diethyl ether and a solution 0.1 g potassium hydroxide in 2 ml water was added. The mixture was stirred at room temperature under nitrogen for one hour. The organic solvent layer was separated and washed with water and filtered through silica gel and then dried and evaporated. The resultant oily product (0.2 g) was sufficiently pure for the next synthetic step. 1H NMR (400 MHz, DMSO) δ 8.05 (d, 1H, J=8.5), 7.81 (d, 1H, J=8.1), 7.67 (d, 1H, J=8.8), 7.59 (t, 2H, J=7.8), 7.43 (dt, 4H, J=6.9, 20.3), 7.22 (t, 1H, J=7.3), 6.75 (d, 1H, J=8.7), 4.05 (d, 1H, J=1.7), 3.88 (d, 1H, J=1.7), 1.71 (s, 6H).
