Water → 5-(Bromomethyl)benzo[d]oxazole

Participants

Reaction Steps

A solution of 5-methylbenzoxazole (0.5 g) in chloroform (20 ml) containing N-bromosuccinimide (0.18 g) and azoisobutyronitrile (0.05 g) was refluxed for 2 hours. After allowing to cool to room temperature the reaction mixture was treated with water (30 ml). The organic phase was separated and the aqueous phase extracted with dichloromethane (30 ml). The combined organic phases were washed with brine (30 ml), dried over magnesium sulphate and evaporated. The residue was triturated with pentane giving the title compound (0.36 g) as an off-white solid, m.p. 90-93° C.
