Asolution containing 0.069 g sodium nitrite (1 mmol) in 10 cm3 water was added dropwise to the initial mixtureduring 40 min. An aqueous solution of aromatic nucleophile(1 mmol) in NaOH 10percent (5 cm3) was then addedand the resulted mixture was stirred for 1 h at 0 C. Theprecipitated solid was filtered, washed with water and dried in air. The products 2a?2c, 2e, 2f, 2m, and 2o were purifiedby recrystallization in ethanol, but preparative TLC (nhexane?EtOAc, 4:1) was applied for purification of products2d, 2g?2l, 2n, and 2p.<\/p>\n<p>These compound has a wide range of applications.
