Reaction Steps

(6-Hydroxy-5-methyl-naphthalen-2-yl)-carbamic acid benzyl ester (Step a, 0.300 g, 0.9 mmol), 4-chloro-6,7-dimethoxy-quinoline (0.218 g, 0.9 mmol), K2CO3 (0.124 g, 0.9 mmol), and copper (4% by wt.) were added to a vial, then microwaved for 30 min at 120° C. with 150 watts of power (Powermax, CEM). The mixture was diluted with CH2Cl2 and 40 mL of 1N NaOH, then extracted the organics 3 times with CH2Cl2. The organics were combined, dried over Na2SO4, filtered, and concentrated in vacuo. The crude was crystallized from CH2Cl2/Hexanes to give a light brown solid, which was the titled compound. MS (ESI, pos. ion) m/z: 361 (M+1). Mass Calc'd for C22H20N2O3: 360.15.
