Versuchsvorschrift

To a solution of 4-chlorobenzonitrile (5.0 g) in methanol (40 ml) was added sodium methoxide (0.20 g) and the reaction was stirred at room temperature for 3 days. Ammonium chloride (1.94 g) was added and the reaction was stirred overnight. The reaction was filtered and the filtrate concentrated to an oil. After the addition of ether the off-white precipitate was collected and dried to give the title compound (3.62 g). Electrospray MS m/z 155 [M+H]+.
