Hydrochloric Acid → N-(2-chloromethoxyethyl)phthalimide

Participants

Reaction Steps

A dispersion of N-(2-hydroxyethyl)phthalimide (19.1 g) and paraformaldehyde (3.0 g) in 1,2-dichloroethane (250 ml) was cooled in an ice-salt-acetone bath and saturated with dry hydrochloric acid with stirring. After 4 hours the mixture was dried over calcium chloride, filtered and evaporated under reduced pressure to give N-(2-chloromethoxyethyl)phthalimide (21.9 g), m.p. 69°-72° C.
