The reaction mixture is diluted with water (50 mL) then evaporated to low bulk and filtered. The solid is washed with water and dried to give 2-(2,4-dibenzyloxyphenoxy)acetamide (1.1 g) as a white powder, m.p. 120° C. [Elemental analysis:- C,73.1; H,5.78; N,3.79%. Calculated:- C,72.7; H,5.83; N,3.85%].
