General procedure: A mixture of nitrile (10 mmol), halohydrocarbons (11 mmol) and FeCl2·4H2O (2 mol %) was placed in a round bottom flask. Then the reaction mixture was heated at 80 C for the given time. After completion of the reaction monitored by thin layer chromatography (TLC), 5 ml water was added into reaction system and extracted with ethyl acetate (3 × 5 ml). The organic layers were collected, combined, washed with water (3 × 10 ml), dried over anhydrous Na2SO4, and concentrated under vacuum. The pure product was obtained by directly passing through a silica gel (200-300 mesh) column using petroleum ether/ethyl acetate and identified by 1HNMR and 13C NMR.

Computed Properties of C7H4FN

The 4chloro-6-(2-methylimidazol-1-yl)quinazoline used as a starting material was obtained as follows: 3-Fluorobenzonitrile (25 g) was added dropwise to a stirred mixture of potassium nitrate (21.1 g) and concentrated sulphuric acid (150 ml) which had been cooled in a mixture of salt and ice. The mixture was stirred at ambient temperature for 45 minutes. The mixture was poured onto ice (800 ml) and the precipitate was isolated. The solid so obtained was dissolved in methylene chloride, dried (MgSO4) and the solution was evaporated to give 5-fluoro-2-nitrobenzonitrile (19 g).
