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) is 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 is evaporated under vacuum. The residue is dissolved with CH2Cl2 (5 mL) and the mixture is filtered. The filtrate is concentrated to afford crude product, which is 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.
