Procedure

N-[2-(3-Amino-4-methoxyphenyl)ethyl]-2,2,2-trifluoro acetamide (5.24 g., 0.02 moles) in acetic anhydride (20 ml) was boiled at reflux for 2 hr. The anhydride was removed under reduced pressure and the syrupy residue added to water. The grey solid was collected and recrystallised from toluene using charcoal to give the sub-title compound as cream crystals (4.0 g) mp 105°-106°.
