Reaction Steps

1-(biphenyl-2-ylmethyl)-2-ethyl-1H-pyrrole, 13: To the crude 12 (14 g, 83 mmol) in dry benzene (200 mL) at room temperature is added biphenyl-2-ylmethanamine solution (100 mmol) and triethylamine (110 mmol). The solution is heated to reach 65° C. and stirred for 18 h. The resulted reaction mixture is filtered and concentrated. The crude product was purified by silica gel chromatography to afford 13
