Participants

Reaction Steps

Using the general procedure, tryptamine (0.160 g, 1.00 mmol) was coupled with iodobenzene (134 μL, 1.20 mmol) using CuI (9.5 mg, 0.050 mmol, 5.0 mol %), K3PO4 (2.1 mmol), trans-N,N′-dimethyl-1,2-cyclohexanediamine (32 μL, 0.20 mmol, 20 mol %) and toluene (1.0 mL) to give the crude product. Column chromatography (2×15 cm, methylene chloride (saturated with ammonia):methanol 50:1) provided 0.206 g (87% yield) of the product as a yellow oil. 1H NMR (400 MHz, CDCl3): δ 7.65 (m, 1H), 7.55 (m, 1H), 7.47 (m, 4H), 7.31 (m, 1H), 7.18 (m, 3H), 3.06 (t, J=7 Hz, 2H), 2.94 (t, J=7 Hz, 2H), 1.40 (bs, 2H).
