Procedure

A mixture of p-iodoanisole (85 mg, 0.36 mmol), anhydrous K3PO4 (102 mg, 0.48 mmol), CuI (4.6 mg, 0.024 mmol) and N,N′-Dimethyl cyclohexane-1,2-diamine (14 mg, 0.096 mmol) was added to 5H-[1,3]dioxolo[4,5-f]indole-7-carbonitrile (45 mg, 0.24 mmol), prepared as described by the method of example 1A, step A, in anhydrous toluene (0.4 mL). After heating at reflux for 24 h, the solvent was evaporated under vacuum. The residue was dissolved with CH2Cl2 (5 mL) and the mixture was filtered. The filtrate was concentrated to afford crude product, which was purified by silica gel chromatography using EtOAc/petroleum ether (1:4) as eluent to yield 5-(4-methoxyphenyl)-5H-[1,3]dioxolo[4,5-f]indole-7-carbonitrile.
