Procedure

To a solution of 82 mg (0.280 mmol) (2-amino-5-propargyloxy-phenyl)-(4-isopropyl-phenyl)-methanone in 3 ml dioxane is added 193 mg (1.40 mmol) potassium carbonate and 119 mg (0.419 mmol) 6-Bromomethyl-2,3-dimethoxy-quinoxaline. The mixture is stirred at 80° C. for two days, diluted with water and extracted with CH2Cl2. Purification of the crude product by chromatography (ethyl acetate/hexanes 1:1) affords a yellow oil.
