Reaction Steps

A mixture of 2-amino-6-bromo-quinolin-4-ol (29.4 g, 0.12 mol), acetic anhydride (36.7 g, 0.36 mol) and sulphuric acid (20 ml) in glacial acetic acid (300 ml) was refluxed for 30 min. The mixture was allowed to cool to rt and then poured into water. The precipitate was isolated by filtration and dried to afford product N-(6-bromo-4-hydroxy-quinolin-2-yl)-acetamide as a brown solid (32 g, 93%). This material was used in the next step without further purification.
