Participants

Reaction Steps

A solution of 1-(4-(2-chlorophenyl)-1-methyl-1H-1,2,3-triazol-5-yl)ethanone (1.02 g, 4.33 mmol) was dissolved in chloroform (7 mL) and acetic (0.136 mL) was heated to reflux and then a solution of bromine (0.234 mL, 4.54 mmol) in chloroform (3 mL) was added dropwise within 10 min at and after 1 h bromine (0.09 mL, 1.73 mmol) in chloroform (2 mL) was added and heated under reflux for 1 h. After cooling to room temperature the mixture was poured onto ice-water and the mixture extracted with dichloromethane. The combined organic extracts were washed with water, brine, dried over sodium sulphate, filtered and evaporated. Purification by chromatography (silica, 10 to 60% ethyl acetate in heptane) afforded the title compound (988 mg, 73%) as an off white solid. MS: m/e=313.9/315.9 [M+H]+.
