Procedure
6-Benzyloxy-4-hydroxy-2-methylquinoline (2.6 g; see step (ii) above) in phosphorus oxychloride (40 mL) was heated at reflux for 3.5 hours. The mixture was then added carefully to ice/water and solid sodium carbonate added until the solution reached pH 8.0. The mixture was extracted with ethyl acetate, washed with water, dried (MgSO4), filtered and evaporated. The resulting solid was triturated with diethyl ether to give the title compound (6.4 g) as a white solid.
