Reaction Steps
1-(3-Amino-2-hydroxy-6-methoxy-phenyl)ethanone (12.9 g) was added to a mixture of acetic acid (3 mls) and water (20 mls) and heated to 60° C. Acetic anhydride (9.5 mls) was then added and the whole heated on a steam bath for thirty minutes. The reaction mixture was poured into water and extracted into ether, which was dried using magnesium sulphate, and after filtration the volatiles were removed in vacuo, affording a golden brown solid which was triturated with chloroform and dried under reduced pressure, yielding 3.7 g of the sub title compound, mp 160°-162° C.
