Procedure
Dry hydrogen chloride gas was passed through a stirred solution of 2-(2-chlorobenzylaminooxymethyl)-2-methylpropanoic acid (2.0 grams; 0.01 mole) in absolute ethanol (100 mL) at ambient temperature for two minutes. The reaction mixture was stirred overnight under a nitrogen atmosphere. The reaction mixture was concentrated under reduced pressure. The residue was purified by passing it through a silica gel column, eluting first with methylene chloride (200 mL) and then with 95:5 methylene chloride:methanol. Appropriate fractions were combined and then concentrated under reduced pressure to afford 0.45 grams of ethyl 2-(2-chlorobenzylaminooxymethyl)-2-methylpropanoate hydrochloride as a colorless gum.
