Reaction Steps

A slurry of 6-hydroxy-naphthalene-1-carboxylic acid (0.100 g, 0.531 mmol), 4-chloro-6,7-dimethoxy-quinoline (0.143 g, 0.638 mmol) and Cs2CO3 (0.519 g, 1.59 mmol) in 2.66 mL of DMSO under argon was stirred for 15 min at RT. The mixture was heated to 140° C. in a microwave. After 1 h, the reaction was diluted with ca. 2.7 mL of water. 6N HCl was added dropwise until the solution was at pH 3-4. The resulting precipitate was filtered and washed with acetone to afford the titled compound as a tan solid.
