YieldReaction ConditionsOperation in experiment
With N-Bromosuccinimide; In water; acetic acid; EXAMPLE 25 4-Bromothiazole A solution of 15 g of 3-(methylthio)thiophene in 60 ml of acetic acid is stirred and cooled 15° C. Twenty and four tenths grams of N-bromosuccinimide is added in portions at a rate so as to maintain the reaction temperature between 15°-17° C. and the reaction is stirred at room temperature for 2.5 hours. The reaction mixture is treated with 75 ml of water, extracted with 600 ml of diethyl ether, the diethyl ether portion is washed with water and then carefully shaken three times with saturated sodium bicarbonate. The diethyl ether layer is washed again with water, dried over sodium sulfate and concentrated in vacuo. The dark green oil was purified by Kugelrohr distillation to give 19.5 g of a pale yellow-green oil, by 74°-78° C. (0.15 mm Hg).
