Trifluoroacetic acid (10 ml; 129 mmol) was added to a stirred solution of N-methylaminoethanol (9.72 g; 129 mmol) in p-xylene (10 ml) at 0° C. The mixture was heated under reflux for 12 hours, then allowed to cool and stand at room temperature overnight. All the volatiles were removed and the product distilled under high vacuum to afford the product as a clear liquid. Yield 9.8 g (44%); b.p. 110° C./1 mm.
