Diazomethane → Methyl 4-(bromomethyl)benzoate

Participants

Reaction Steps

Diazomethane was added slowly to a suspension of 10 g of 4-(bromomethyl)-benzoic acid in 50 ml of methylene chloride until a persistent yellow coloring of the medium was obtained and excess diazomethane was destroyed by the addition of acetic acid. The mixture was evaporated to dryness and the residue was washed with water and dried under reduced pressure at ambient temperature to obtain 9.25 g of the desired product melting at 54° C.
