Reaction Conditions

Reaction Steps

A 1-liter flask was charged with 43.9 g (0.51 mol) of 3-methyl-2-buten-1-ol, 51.6 g (0.51 mol) of triethylamine and 300 ml of dichloromethane, and the mixture was cooled down to 0° C. While stirring the mixture at 0° C., 100.9 g (0.50 mol) of bromoacetyl bromide were added dropwise over 1 hour, followed by stirring further for 3 hours at room temperature. Solids were separated by filtration from the resultant reaction mixture, and the filtrate was washed 3 times with water and distilled to obtain 66.5 g of 3-methyl-2-butenyl bromoacetate.
