Reaction Steps

Hydrogen bromide solution (33 wt. % in acetic acid) (17.8 ml, 98.92 mmol) was added dropwise to 3-hydroxy-3-methyl-pentanedinitrile (3.07 g, 24.73 mmol) with stirring. The reaction was stirred overnight at room temperature. Saturated aqueous sodium hydrogencarbonate was added until neutralised. The resulting white precipitate was collected by filtration, washed with water and dried under vacuum to give the desired product. Yield 2.55 g, 55%. LCMS MI: 186.89+188.91, RT: 3.16 min, Method: 2.
