Reaction Steps
2-Chloro-6-morpholin-4-yl-pyran-4-one (7.98 g, 37 mmol), (3-methoxycarbonylphenyl) boronic acid (8.01 g, 44.5 mmol), and ground potassium carbonate (11.23 g, 81.40 mmol) were suspended in dioxane (50 ml) and degassed (sonication for 5 min then saturated with N2). Pd(PPh3)4 (2.13 g, 1.85 mmol) was then added and the reaction mixture was then heated at 90° C. for 24 hrs under a vigorous stirring and a N2 atmosphere. The solvent were removed in vacuo and the residue was then suspended in water 50 ml) and extracted with ethyl acetate (100 ml). The organics were combined, washed with saturated brine and dried over sodium sulphate. The solvent was removed in vaccuo and the residue was purified by column chromatography (silica; dichloromethane:methanol; 9:1) to give the title compound as a white solid (5.42 g, 46%). m/z (LC-MS, ESP): 316 (M++1).
