Reaction Steps

2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indol-1-one (I-61e: 250 mg, 1.34 mmol) was reacted with 3-iodo-4-methylpyridine (294.3 mg, 1.34 mmol), 1,4-dioxane (10 mL), copper iodide (25.6 mg, 0.134 mmol), trans-N,N′-dimethyl-cyclohexyl-1,2-diamine (59.8 mg, 0.402 mmol) and potassium phosphate (710 mg, 3.35 mmol) at 120° C. overnight to afford the crude product. Purification by column chromatography on silica gel (40% ethyl acetate in hexane), followed by preparative HPLC afforded 5 mg of the product (2% yield).
