Procedure

A solution of sodium hydroxide (0.08 g, 0.0020 mol) in water (20 cm3) was added dropwise to a solution of 4-[6-(4-nonylphenyl)benzothiazol-2yl]phenol (0.42 g, 0.0010 mol) in methanol (50 cm3). The 6-bromohexanol (0.18 g, 0.001 mol) was then added dropwise, followed by the potassium iodide (0.02 g, 0.00125 mol) in one portion. The reaction mixture was heated under reflux overnight and the poured onto a mixture of water (100 cm3) and 10% hydrochloric acid (20 cm3). The resultant precipitate was filtered off and recrystallised from ethanol to yield 0.31 g (62%) of the pure compound.
